The most overrated films that come to mind...
Fight Club - This movie was so boring that I had to watch it in two separate sittings. The first time I watched it for an hour and had to stop because it just about put me to sleep. Eventually I got around to watching the second half, and it was even more disappointing than I had anticipated. Also, it's hard to take any movie with Brad Pitt seriously. He's such a worthless hack.
Inception - This was just pain bad… typical Hollywood special effects in place of a good story. They introduce all these characters whom the audience never really gets to know, and the token female character ends up being utterly pointless by the end. On top of that, the plot was very poorly devised. The premise of a dream within a dream is a rather cool idea, but they completely ruined it with flawed logic and cheesy gunfights.
Eternal Spotless Mind blah blah blah… whatever it was called - Again, all special effects and a silly plot.
Pulp Fiction - It only received the attention it did because Reservoir Dogs was so good. Unlike Reservoir Dogs, however, Pulp Fiction has a stupid plot and extremely overrated actors. Bruce Willis is so cheesy, only ever able to play himself: a big, dumb guy. The other guys weren't much better.
Kill Bill – same as above. Pretty much the only thing Tarantino ever did that was truly worth a damn was Reservoir Dogs.
Revenge of the Sith – In order for Anakin's fall to be truly sad and tragic (as it was originally described in the first film), he has to actually be liked first. Instead, he was just a whiny, annoying d-bag, and that was before he became evil. Instead of feeling sorry for him when he was all burnt and crispy, the audience was cheering for Obi-Wan to finish him off. Epic fail.
Also, virtually every comedy that is popular - They usually have one or two funny jokes (at most) that are shown in the trailers, and the rest of the movie is just plain dumb. This describes pretty much every comedy that has come out in modern memory.
