Unnecessary Comparisons
While watching the trailer for this, the thought of Buried did pop into my head. Buried however didn't intrigue me. So do I want to watch a similar film? Maybe. But this thread isn't about that.
Why do you guys have to rip on a movie just because it's similar to another one. Why can't you just enjoy both films as two different products of two different companies?
Watch the movie. Don't watch the movie. You're probably missing out if all you're going to do is compare it to something that's already been released.
