I hate being the reflexive defender of this movie, but I guess I will be once again. This Kirk is not the Kirk of the original series. He takes his cues much more from the Kirks of Star Trek II through VI. That Kirk wasn't the Kirk of the original series either. He certainly isn't mealy mouthed little Wesley either. He's lived a different life and events have shaped him differently. He's also 28. He's not a boy. He steps up in crisis. He acts provocative but turns that quality into a strength. I myself thought much more could be done with this new Kirk, but that's just it. He's got a new trail to blaze. The essence of the original character is there, but he's being interpreted by another actor.
