I think it can happen. I believe that once an actor shows that he is credible (believable), he fulfills his purpose as a good actor. I mainly made this thread to discuss great performances in bad films, if you believe that may be the case. I've seen some people who will hate a film, and hate every single thing about it. They somehow are unable to find not one redeeming factor in it (cough*fanboy*cough*), and dismiss the whole film. I'll tell an example of one of my opinions on the matter. I Am Legend had moderately good reviews, and was somewhat mixed. I thought the movie was a good 3 out of 4 star film, despite not being true to the book, which I didn't care 2 cents about. It had many heavily flawed, but one of the things that was great was Will Smith's performance. Nobody is right or wrong with liking or not liking his performance, but I thought that his performance was amazing, and saved the film from certain doom. Feel free to bring up examples of great performances in bad films, and also discuss whether it can happen or not. Remember that this thread isn't to point the finger that somebody or say that someone is right or wrong.
