The trouble I have with Kirk-2009 is:
• His car theft scene as a snot-ass ten year old shows us the most insufferable little piece of sh-- I can ever recall in a movie. Yes, people in real life are stupid at that age, but choosing to show it in the film makes his snot-assery deliberate and significant. I hate it, and that's not young Kirk to me, whatsoever. That was his no-good neighbor, giving a false name to the cops.
• When he joins Starfleet, he does irresponsible things, and yet somehow flies up the ladder so fast that they give him command of a capital ship, fresh out of the academy. It defies belief.
