Slow, tedious, predictable (and is the IMDb average rating rigged?)

Rating: 4/10 (9 April 2012)

The main reason I'm writing this review is that I'm regular user of IMDb for assessing the quality of a movie before choosing to watch it. At the time of writing this review The Hunger Games had an average score of 7.7 from over 84,000 "users". I find this score of 7.7 hard to believe after watching the movie, and especially after reading other written IMDb user reviews which all seem to be negative (so is there a bot at work here or some other manipulation going on?). Generally in the past I've found the IMDb average rating a reliable indicator of the quality of a movie, but that is simply not the case for this movie.
I think I being generous in giving this movie a score of 4. This is a long tedious predictable bore of a movie. Sure, I'm 36 years old so perhaps I'm not the target demographic, but I am in no way a movie snob. I enjoy science fiction, but I came out of this movie feeling that this movie was a lost opportunity - it could of been so much better. I've never read the books, but after reading many of the user reviews here I plan to, as it sounds like the books treat this story with a lot more depth. Unfortunately I feel the movie is shallow, superficial and way too predictable.
