I wasn't saying I dislike Aqua Teen, just that I expect a lot from a Gainax show, and that made me unable to enjoy PSG. It's funny really, I get mad at other people for doing this, and here I am doing it myself. It's really because I'm very emotionally attached to Gainax because of the things they've produced. Evangelion, FLCL, Diebuster, Mahoromatic, and Kare Kano sort of got me through my adolescence. Gurren Lagann was after that period of my life, but was an excellent capstone thesis to the rest of the work they had done in mecha.
And yeah, He Is My Master is pretty generic. I'm assuming here, but you probably just haven't seen a lot of shows like this because they're not usually very high profile. Dozens of shows get produced every season that go under the radar of pretty much everyone in the western fan community. No one would have ever heard of He Is My Master if it hadn't been made by such a prestigious studio. Just look at how much more creative and well thought out Mahoromatic is.
