Re: Revisiting the films...
Hard to put my finger on jyst what it is, but his mannerism's and delivery of lines seems more like Shatner than Kirk to me. I don't know how much of this is the fault of the script he was given, but it definitely bugs me when I watch.
I've had much the same feeling. Some of it may indeed have something to do with the scripts. In TFF it's Shatner directing himself so how objective could he have been in regard to his own performance?
STAR TREK: 1964-1991, 2013-?
