Yeah, I tend to agree with Mirrorball Man on this one. Stage acting is very different from acting in front of a camera. Actors who are used to performing on stage are in danger of appearing too dramatic on camera, if they're not careful. Even Patrick Stewart, one of my favorite actors ever, was guilty of hamming it up a few times on TNG. He's fantastic in his Shakespearean roles. But not every role requires that kind of acting.
