I love the show Onegai Teacher... It has a good deal of fanservice, too much for some people, but I love it... (the show, not the fanservice) The show deals with good issues, and deals with them better than American TV shows do. It has a surprisingly heartwarming plot, and the main 12 episodes end rather well... (no comment on the 13th... It was really unnecissary.) It's really sad that it had to be tainted by that fanservice...
I have been looking for any sort of official stuff on Teacher, and I realize why so many people here hold such a strong objection to it without even watching it: The official art is much more fanservicy than the show ever gets... Who's to know why they held back, but the official art makes it look like some sort of sex anime. Shots of open shirts and underwear and all sorts of things that were never in the show... (not to mention that the shots from the show are all the fanservice ones...)
Why does this happen? The extended sountrack for Silent Hill 3 featured a picture of Heather with her shirt unbuttoned, no bra, but she dresses rather conservatively throughout the game... I wonder why it is often so different in the secondary art than it is in the actual product? Are they just trying to catch people's eyes? Do they think they'll draw more people if they tempt them with that, and then spring the actual plot on them when they've been trapped?
I've seen similar things in Nadesico too... Probably others, but I can't think of them right now... I just don't get it...
