IMDb, Seriously 8.0 rating for this stupid movie?

Rating: 1/10 (7 January 2013)

There are like 30% good reviews and 70% bad reviews but still this movie holds 8.0 rating in IMDb. How is that possible? I am a fan of Naomi watts and i liked Ring and Eastern promises. When i was going through her biodata, it said that Mulholland Dr was the best movie in her career. I gave it a thought and downloaded the movie. What followed was 2.5 hrs for utter boredom and some seriously weird stuff. I was like "Oh the movie is slow. But it will catch up..". This was my thought for almost 2 hrs. This 2 hrs had some odd scenes like The guy in the wheel chair who face was really bent out of shape, the stupid director who poured paint in his wife's jewels after seeing her sleeping with the pool boy, a rehearsal scene with Naomi intimately kissing this old guy and the crazy club silencio scene. I was like "What the hell?". I thought the director had an answer in the last half hour. But the last half hour was even more bizarre than the first 2 hrs. Here we are introduced to a new storyline which contradicts to most of the first 2 hrs. And suddenly the creepy old couple come in and scare the lead character to shoot herself and the movie ends. I have never been this frustrated my whole life, even when i failed for the first time, in AI in college. I read some of the good reviews and it said that we need to watch at least twice to fully understand it. A movie is something which should give a closure when it ends, how complicated the storyline maybe (Eg.Inception, Memento etc.,) But this movie was pure rubbish. Although for some scenes there maybe some valid reasons to be there in the dream, but some parts in the dream absolutely made no sense, like the hit-man's botched kills, the disfigured guy behind winkie's, the blue box, the guy in the wheelchair, Adam's childish/insane acts etc., The reviewers are saying that these are made up by Diane's mind. Did they tell that in the movie? I can't believe people are really defending this bad movie with some of their own interpretation when actually the director should have done that. A director can make one or two scenes or maybe the ending with no proper closure so that the audience may interpret it their own way (Inception, Eastern promises, Wrestler etc.,) but not the entire movie?!??! I know i have seen lot of bad movies, but this is the worst and definitely this doesn't belong in the top 250 among the Greats!
