I would like to get this out of the way, this is a COMEDY. The biggest complaints come from people who are taking this show too seriously or question the logic in some situations.
Story: Our mc, Hiro, goes to the store to purchase the brand new version of a game. Short on cash, he's instead coerced into buying a shitty dead Full Dive RPG game known for being 'too realistic'. Hiro suffers during his quests while playing Full Dive but a portion of the story takes place outside of the game as he logs in and out. The pace so far is slow and steady. There is a dark/serious undertone so some may feel that it clashes with the comedy, personally I didn't mind it. There is potential growth from Hiro due to his backstory and there are lingering questions that have yet to be answered. The timing in addition to the voice acting made the comedy enjoyable. Overall the story is not completely generic but nothing special at the moment. 6/10.
Art: I love the art style and colors. It's clean and pleasing to look at. The animation is good but a few times I noticed it could have been better. The character designs aren't really unique but I do enjoy Reona's. 7/10.
Sound: The voice acting is superb, the seiyuu's did an excellent job across the board. The OST isn't a stand out but works. The op and ed are catchy. 8/10.
Character: There hasn't been much time devoted to the characters other than Hiro. They have been briefly introduced without having much depth. Some may find one specific character unlikable and I think the author did an excellent job building frustration over time until you and our mc has had enough with them. The characters aren't the smartest bunch either. Despite their interactions being entertaining, the 1-dimensional aspect and being a bit generic leads to an average score. 5/10.
Enjoyment: I'm having a lot of fun with the slow pacing, comedy, the 'too realistic' RPG setting, and the fact that it has moments outside of the game as well. If you're looking for everything to be logical, have an ultra serious tone, or don't want to see our mc suffer for the sake of laughs, I would avoid Full Dive. I think it's something you turn your brain off, sit back, and enjoy. 7/10.
Final thoughts: Full Dive may not be for everyone but as a comedy it's worth checking out. So far it's excelling at voice acting and comedy; the characters haven't been anything special though they have potential to improve.
