You know what can really make or break a movie, expectations. It can be really unfair to a movie. Some get overhyped but are still good. My room mate thought The Hurt Locker was okay but only because he had heard it was suppose to be fantastic. Without thinking expecting such, would he have thought it was fantastic? Others get nearly no mention and go undiscovered. (More people need to rent Sugar.) With the digital age, films have their fates decided for them after the first weekend of release.
The other week I watched a film called Stay. All I know about it at the time was Ewan McGregor was in it. I had no idea what it was about and I didn't remember anyone ever telling me whether it was good or bad. My mind was cleansed of any sort of expectations. I thought it was fantastic. The narrative was unique and each shot was rich in composition. I wonder what my opinion of it had been had I known anything else about it before hand. I also wonder if I wouldn't have hated Van Helsing so much if I didn't think it was going to be a cinematic masterpiece. (I still would.)
I'm starting to think that for a film to have a complete effect on you, you have to know nothing about it beforehand. Forget knowing who's in it, who directed it or even what it is about. People write off a movie as being dumb just from hearing the concept. Some people are turned off of a movie just because a certain actor is in it. An ex-girlfriend of mine wouldn't see Batman Begins because Katie Holmes was in it. That's not very fair to everyone else who worked on the film. Actors get stuck with stinky scripts and directors get stuck with numbskull actors.
I know this might be a challenge but I want you to try it anyway. Watch a movie that you have never heard of and watch it without hearing anything about it beforehand. It's pretty fun. You get to decide what type of movie it is instead of what type of movie it was marketed as. You get to decide whether it had a good director before even knowing his/her name. You'll find it to be an enlightening experience.
