Me and my girlfriend are both Persona fans, so when we saw the first TV series and realized it had little to do with the games, we were a little disappointed, yet we enjoyed the little Easter-eggs with in the show referencing the games (persona 3 more than 4 at the time) we got quite far into the show before we lost interest.
However when we heard about a persona 4 TV series we were somewhat hyped and began watching it, but the fast paced rushing through the story and character models looking off were jarring, about 4 or 5 episodes in we gave up on the series and stuck with the game. It could be nit picking, but honestly when the character models look off so much it's almost like they are really looking for that BluRay cash in.
I understand that animating is difficult but what made thing even more jarring is the fact most of these model checks (or lack there of) were frames where characters don't move much, making the errors the focus of attention. It was enough to put me off the series. Persona 4 anime isn't the only one guilty of this sort of thing, many animes have issues exactly like it, but I recall years ago anime had a certain quality that is sort of lacking in today's standards. It's sad to see anime stoop to a low, holding back its quality for a second monetary gain.
