The first movie that comes to mind is The Departed. The second is Goodfellas. I know I will be flamed for it, but I find the films severely overrated. Especially The Departed, while watching it I wanted to shoot myself because I was thinking "this is... so... long...", and then I would look at how far I was through the movie only to think "another hour?!?!?! NOOOOOOOO!"
The Godfather: Part II was also very long and I didn't even finish it in one sitting because of it. Although, I do understand why it is so revered and can appreciate it nonetheless.
I feel sorry for anyone who watches Goodfellas and finds it boring, films like that have an 'energy' about them which reminds you of just why you go to watch films.

I found Polanskis Fearless Vampire Killers and Ghostbusters awfully boring. Both shine with no suspense, lame and corny jokes and tedious "Action"
The Avengers (my worst movie of all time)
The 51st State
Mickey Blue Eyes
Meet Joe Black
About Schmidt
A serious Man
