Not the OP, but thought I'd reply to keep the thread bumped. The only work I've watched from him is Touch (and the sequel Mix) and I enjoyed Touch quite a bit, although found it to be very boring for the first 50 episodes. When the coach is introduced in the third season I found it to be really fucking good and was surprised all the anime needed was a character like this to be an antagonist and make the team have to STRUGGLE to win some of their games with his random restrictions he would place on them
The movies (and Mix but that's not retro) are kinda bad and I'm not sure what the point of them was. The first movie forces TONS of drama between the main characters and the side characters all feel and have the same intentions despite being like 5 years later and the second movie just moves everyone to America for some reason and that's about it. (Although, this scene will always be hilarious for having a character named Chad, with women chanting his name doing a Chad move to allow a runner to get home.)
I do want to watch/read more of his work, but I was pretty baseball'd out when I finished Touch/Mix so I might go back to it this year. H2 seems like it could be pretty fun so I'll give that a shot.
