Affleck isn't all too convincing I would say. As for Slater, I only saw him in Broken Arrow and Travolta sucked so bad in that one he made Slater look good, otherwise I don't know what he's like.
Travolta is someone else wo seems to act in a lotta nonsense and am i the only one who thought Face/off would have been a much cooler film if Nicholas Cage was made the bad guy the longest in the film and not 1/4 into the film make him the good guy
