Only someone who knows nothing about film would consider this the worst.
This film sucked, I would give it a 3/10. But please use your head when examining films! This film was competently shot, the lighting was fine, the sound mixing was reasonable. That ALONE makes it nowhere near the worst film ever made when you compare it to the thousands of garbage b-z grade films, pretentious indie films, bland-by-the-numbers found footage horror films like 'The Devil Inside', or garbage propaganda docos about how 9/11 was an inside job.
Just because people hate "Beniffer" or whatever, that is an OUTSIDE reason to dislike a film. Yes, the acting for the most part sucked (especially Bartha's embarrassing performance), it was awkward and had some of the worst uses of music I've ever seen in a mainstream film. But do you forget the really enjoyable Pacino scene? Or the ridiculous Walken scene? Those alone have more entertainment values than many films. Some of the dialogue actually was genuinely good, and the stars were eat least trying.
So please, yes it sucked. But THINK before you go around giving films 1/10's. Those should only be preserved for extremely rare cases. Even films I LOATHE like "Identity Theif", "Just go with it" or "TDKR" I rate based on ALL factors.
If you rate this film on all merits, only a total juvenile moron would rate it a one out of ten or even CONSIDER it to be NEAR the worst movies ever.
