Its not fair to compare movies to anime. In Japan its huge, but anime is still a small market in America, despite the millions of new viewers that have been tuning in, in the last 10 years. There are more people in America that know what Star Trek is and not know what anime is. So anime viewers as a whole are still a small community here in the states. So like comic book conventions or robot conventions, you have to have a variety of things available for the anime community. It might seem broad, but I don't think you will ever see an anime convention for just people that like romantic comedies, well at least not here in the US. So until more people are watching anime instead of Star Trek or porn, take what you can get.
