Movies that you feel were miscast but no-one else does

For some reason, from the first time I saw Troy, I found Brad Pitt not believable in the role. In fact when Sean Bean appeared, I felt he would have been better suited. I like a lot of Brads films but here I felt he was trying to convince the audience he was this unbeatable god, I didn’t feel it at all. I just felt he was too pretty and putting on a tough voice. Yet whenever I talk to anyone about this, the main response is that he was great and looked the part! Are there any instances you get this, a real feeling an actor is not right, but somehow everyone else thinks they are great!
