Incidentally, I've just gone on a dropping spree continuing up to now. So far, this week I dropped:
Murabito Desu ga Nani Ka - Well, pretty much for the same reasons I listed
here: unnecessarily complex, poor storytelling, horrible character development. Finally got around to bookmarking Kumo desu ga instead.
Shield Hero - terrible progression, downright annoying characters, lack of creative use of powers along with the stale, overused tropes by an uninteresting lead, and the nail to the coffin, a dreadfully dragged out grudge with no real significant impact to anything other than the MCs perspective of fairness.
One Piece - this one's a while back--think years ago--but I feel like I need to put it out here for closure's sake lol needed to do thesis. by the time i got the time again, i missed like close to 40+ chapters. Dropped it. The characters don't change personalities much, if they even do anyway. That was made clear to me when Zoro tried to get Mihawk to be his mentor and again when Ace died. Sure, some of the dynamics change, but their core values stay the same so you can pretty much guess what they'll try to do when confronted with a situation. They only ever just get stronger. I was in it for the powers and the fights. Not really interested in one piece, the treasure, since they hint so little of it it felt more like a plot device rather than being the core plot so the allure of mystery was lost to me. I could be wrong since I stopped reading it and all, but eh. I'm already hundreds of chapters behind.
How I Came To Like My Male Friend - it's not funny, imo, even when the premise sounds like it would be.
The Justice of a Villainous Woman - listed the reasons
here. Gist of what I wrote is that it got progressively got worse in every aspect to the point that it was generous of me to even give it a rating of 3/10.
Isekai Nonbiri Nouka - about to at least. It's getting really boring. He's already practically gotten the entire continent on his side. He's just gonna introduce modern concepts and technologies for them. Things I'd do better off searching online and others that is theoretically a good idea unless someone messes up, which would never seem to happen.
Parallel Paradise - I admit, I originally went for this for post-clarity's sake, but got intrigued by the mystery. Over time though, the dude just became a living date-rape drug and I was starting to get pissed off at how he tackled problems. He got progressively more arrogant when in essence, him being there caused more problems than he'd solved. But having already switched perspectives on it, I couldn't use it as material anymore either. Completely lost interest.
Kanojo, Okarishimasu - While I don't particularly mind beta MLs, this guy's just terrible and annoying. I kinda feel sorry for the girl with how much of an ass this guy is. I suppose he eventually gets better, but I just couldn't tolerate him anymore and dropped it.
Gleipnir - the translations and the uploads got janky for a while and I couldn't take it. By the time I was told there were better ones out, my depression'd already kicked me in the gutter. Supposedly, I can't handle darker themes anymore so I dropped it along with others at my doc's advice.
The Twin Siblings’ New Life - same reason as gleipnir. Story progression's just gotten too janky for me, too, that I can't take it anymore.
Maou Gakuin no Futekigousha - it's just not my cup of tea. I find the MC uninteresting. I got a few smirks here and there, but eh.
Saving 80,000 Gold Coins in the Different World for My Old Age - I was in it for how she'd develop her relationships with the people in the otherworld. I already had low expectations about how she goes about being smart and all that, but then it shifted focus from her relationships between the 2 worlds to how she's exploiting both worlds because everyone there is apparently incompetent. Including the MC. Which is weird because she's supposed to be smart, and at first she was. Then I guess the author didn't know how to outdo the last thing. Kinda went all over the place and pulled a murabito desu ga on me.
A-Rank Boukensha no Slow Life - it's lackluster. not my cup of tea. kinda boring.
Boruto - I can't. Everything about it's starting to annoy me. I already had problems with Naruto but this one tried to one-up it. It feels like a waste. Maybe I've been spoiled by Basilisk.
Dragon Ball Super - I'm glad their trying out new things, but I really don't like how things are going for the rest of the cast. I don't find Frieza to be a compelling villain, let alone as an ally. It's nice that Goku's back on the whole "I wanna be the very best" train again, but it seems like the story focuses more on transformations than actual technique. I thought Ultra Instinct was a technique not a form, but they're practically treating it like a form. There are no new techniques, everyone just go "haha, brrrr" and then poof! New enemy. The only thing that kept me going before dropping it were the tidbits of their mundane lives. I personally would enjoy Gohan's school arc pre-cell and similar events, and I think would even prefer it over ToP and the black goku arc. The series now looks like a glorified lightshow to me.
One Punch Man S2 anime - the transition between scenes felt off, the fight scenes lack any oomph to them and the jokes were awfully rendered.
Charlotte and Her 5 Disciples - it stopped being cutely humorous, i'm not invested in any of the characters, and none of them gives off any feeling of command despite supposedly being the best of the best.
In Another World With My Smartphone - the poor use of his powers turned me off and his ladies show no real promise of being anything other than eye candy.
Kenja no Mago - ah this one takes the cake for having triggered me the most, mostly because it is the quintessential example of what I dislike about most fantasy isekais. It's not like none of them are incapable of what he's doing. They just "never thought of it". The worst part is that even the MC isn't even that smart. He just replaces all the complexities of science with magic and it miraculously works.
This manga had an entire world be completely and utterly dim that they are oblivious even to the basic operations of the magic they themselves use. You can't tell me they don't know. They clearly do since that's how you're supposed to invoke magic, and they even describe to shin what he's currently doing as they observe his magic manifest which means they have words for it, too, and being able to directly translate an observed phenomena into language means that it's a concept you're already familiar with begin with. If the only requirement is being able to picture it in your head, then having a word for it means you can already do more than just imagine it.
Example, his boots literally just says air jet. No other mechanism of propulsion at all. If any of them just thought to add "spring", "push", "fly", "surge" while imagining the effect, they could achieve this just as easily. Language itself is not important but your mental image of the effect as you engrave it is. Literally write a line to save on runes and it's all still well and dandy. So how would you improve the sword relying only on that world's knowledge? Walk up to a blacksmith, ask what makes a sword sharp, engrave "sharp" with you imagining cutting smoothly and voila, an immensely simple yet infinitely more effective sword without need for our "modern, sophisticated" knowledge. Again, I don't mind unreasonable OP MCs, but i find writers needing to dumb down the rest of the world for the MC to shine unenjoyable.
