I think if you play a character that is fearless, then it's boring. I think that's what was so incredible about Harrison Ford, is that he always seemed like he was never going to survive it, he's always scared, and yet he always does survive it somehow.
I've had a tough time with Pynchon. I liked him very much when I first read him. I liked him less with each book. He got denser and more complex in a way that didn't really pay off.
