@LouisTheLuis you confusing CHEAP and DIFFERENT. And I can tell the differences between those two. And they pointed out, that THIS is not some cheap anime, when Love Letter - is. In cheap - year, they just dont bother to add details, animations, background etc. And yeah, sometimes details even better in anime but they have the style of the original.
Just for the example - Kimetsu no Yaiba - manga artstyle is not that good, bcs of no experience from author, but anime preserve the style and rise it above.
On other hand - Black Clover - character design looks a like and Studio Parrot have tons of experience in shonen, but anime adaptation is just cheap piece of shit. Or another example - Tokyo Ghoul - first two seasons from Parrot was greatly animated. And then seasons 3 and 4 - cheap pieces of shit. Etc. I hope you've got my point. You cant do exactly the same as author just bcs is just impossible for different people to draw the same, BUT - you can do as close to the original as you could, to preserve original style that all fans loves, you can improve it, by adding details, you can do worse, by doing poor and cheap work without enough details, BUT YOU CANT DO TOTALLY DIFFERENT CHARACTERS JUST BCS ITS MORE POPULAR IN OUR DAYS THAT MEN NOT MUSCULAR LIKE IN ORIGINAL THEY NEED TO BE MORE SEXY.
The whole point of remarks - that this characters couldn't swing swords with this body build, and this kind of realism I guess is what driven the author and what's fans appreciate (beside the story). At least that's my point of view. I wouldn't want to watch anime where characters looks totally different from manga. Death note shitty adaptation with black L was enough for me... 🤦🏻♂️
