Shatner in TOS, which is really weird to say because he's an excellent actor in everything else but Star Trek.
I actually agree with this statement. For a time I used to get really bewildered at all the praise that Shatner would get on this board, as if people were just kissing his butt out of favoritism more than anything else. But name another prominent show or film with Shatner and it's great. Denny Crane!
Don't get me wrong, I'm still a fan and I think he does his job in TOS. But TOS-Shatner isn't his best work imo.
Maybe this is why nuKirk got to be captain so fast -- the higher-ups knew that if he didn't get the ship, THIS would happen
