Though, that isn't completely truthful. I think Parts 1 and 2 were masterfully recreated, but David dived into the money pit from Part 3 onwards.
Part 3 was extended far too long and should've been about 10-12 episodes shorter since that's closer to the real length than Part 4, which is about 20 chapters longer than the Part 3 manga? It made the latter parts of Part 3 really lackluster, not in the sense that it was pacing on for too long (it was, but it wasn't terrible), but in the sense that you could tell theb udget was diminishing really fast. Then Part 4 had terrible management, a shoddy animation studio, and had a lot of really bad moments and unnecessary changes to character designs, like
The hell am I looking at?
The color contrast is also thing I don't like. Parts 1 & 2 were vibrant and colorful, and while Parts 3 and 4 shared the same, they were bleak in their defaults. A lot of browns and blacks, and in Part 4 piss yellows. Of course they had their flare here and there, but honestly I dislike the presentation in 3 & 4, but I'm a fan of how they treated Parts 1 & 2.
Part 5 apparently has even
worse management and lost the director that made some parts of Part 4 bearable to look at (the Ratt episode was really good and detailed actually but that's mostly due to the special guest director that helped), and although the preview has its moments and they're going in a better art direction, I can't say it'll look pretty in the endgame. I'd just read the manga. That's what I've been doing since 2013.
