@monkey123 The "anime", if i can even call it that, is a mess in terms of pacing. Instead of trying to introduce Hajime from the very beginning and make us sympathize with him, it immediately dove straight into the moment he "fell". Not only that, the events are continuously intertwined into one another, making things very confusing to follow and enjoy. It went from "Hajime fell" -> "Meet the monsters" -> Flashback to his study on the other world and learning about Holy Water (without telling us beforehand that this is an isekai btw) -> Return to the present where he regained consciousness -> Flashback to when the group met the Behemoth -> Return to the present of him wondering why he fell -> Flashback to him being hit by a fireball -> Return to the present of him despairing -> Flashback to Kaori's promise to protect him. This kind of constant switching between timelines makes the pacing downright horrible, with no organic transition and logical reordering of events. Not only that, the anime completely glossed over the details of Hajime being an "otaku" back in Japan, his class getting isekaied, and Ishtar (The Priest) along The King's Introductions.
Another disappointing thing is that the animation was extremely subpar, especially during the OP. There was no actual movements at all from any characters, just a slide show with some visual effects added on top. There was this one moment in the OP where the perspectives slowly closed in on Shia's ass, and it made me cringe. The CGI Behemoth and Skeletons were average at best, but they looked really weird while moving (most noticeably when the Behemoth was getting bombarded, or when it tried to get rid of the Transmutaion). What's worse, though, is the CGI magic and CGI boulders/walls, those were actually painful to watch. They looked like piles of goo slowly rising up from underneath rather than actual walls and rocks being created. The Ending sequence was nothing more than a Windows ME screensaver of two light dots dancing around the screen. Hajime running around with his shit-eating grin half way into the episode didn't really enhance the experience either, and only made him look edgier than needed. There is a difference between being confident and acting like a complete nutjob. His edginess is further emphasized when he verbally named his new gun, while in both the manga and LNs, they completely skipped over this part. And then we reached maximum edge when he ate the bear's severed hand in the midst of battle, for seemingly no reason at all. Keep in mind, the anime skipped over Hajime's inner monologues, so this visual exchange made him look edgier out of nowhere. The fact that he felt pain after eating the bear meat was also glossed over, so this just looks like one of those Rule of Cool moments even though it's unnecessary.
