Can somebody explain why this movie gets more than 5?

Rating: 2/10 (4 November 2004)

I just finished watching dawn of the dead and i am terribly sorry for the time i wasted. My first thought was, why don't i log on to IMDb.com and see the rating?? And i see a rating of 7+!!! What the hell?? This movie is a complete waste of time to watch. Everything is set up, and you can tell that every scene. I mean, one moment all the dead are overflowing in the streets, and the next moment there are only 5. Or on one moment they can smell the living from very far, and the second moment they can't track a living human 5 meters away, until they hear a noise coming from there. And these are just some examples. The movie is full of Hollywood clichés.
Go see fight club. Don't waste your time.
