It's true that Shatner overacts and that he hardly has more than three or four gestures and poses (by far many more than Richard Gere, if you come to think of it). But it's also true that no one plays the Enterprise Captain like him. I always tend to see Patrick Stewart holding a battleaxe and embracing his daughter young Guinevere in Boorman's "Excalibur" rather than boldly going where no one (except Jim) has gone before.
