Query: Plan 9 Bad: is Good

This movie was terrible and I love every minute of it. It had a "Hey kids, let's put on a show." type of feel which made it fun. As far as being the worst movie ever made. That's probably still up for debate. There have been a lot of films made since then that have been pretty bad. Freddie Got Fingered, The Postman, Glitter, and Battlefield Earth to name a few. If you go in with an understanding of the story behind Plan 9 you'll enjoy the movie more.
