Titanic. It might have won multiple Oscars but it was Godawful.
Rocky
When Harry Met Sally
My reaction to both: "That's it?"
Dances With Wolves
Full of odd, eccentric, downright goofy moments for a "serious epic." I also didn't care much for the way the star was made such a noble hero figure.
I have never quite understood how The Shawshank Redemption seems to have found its way to the top of everybodies favourites list. I don't hate it but i find it a trifle with not much to say. Forrest Gump I actually loathe though as it strikes me as 2 hour 20 minutes celebration of passive stupidity.
Saving Private Ryan
Since I do not want to offend anyone, I shall refrain from saying why.
Oh, and Braveheart.
Though, from what I hear, it was mostly American critics that liked it so much. The rest of the world did not take to it because, well, history.
