This movie is a paradox. It's so terrible. There's Kevin Costner's vanishing accent to be sure but it's worse than that. The biggest problem is that Costner, Mastrantonio and Freeman are acting in a self-serious period piece while everyone else (most deliciously Alan Rickman, Christian Slater and Michael McShane as Friar Tuck) are acting in a campy folk tale. Also, I hope Costner's hair won a Golden Raspberry for worst supporting actor in 1991.
So what's the paradox? By the end, it's just so damn fun. The sword fights, the bows, the camera shots that ride the air with the arrows and the final siege on the castle to save Marian completely suck me in and I'm on the edge of my seat no matter how many times I've seen this before.
Through one hour, I was wondering what in the world I loved about this movie as a child while the second hour brought it all back.
