@raining51: Definitely give the cartoon a go too, at least for the first season or two. After that, things fall off pretty quick. The original movie is the perfect template for popcorn filmmaking.
@kingodin11: I've wanted one of the movies or cartoon episodes to address the ethics of trapping ghosts for years. There's a magazine cover in the first movie that suggests the debate, but that's as far as things got.
