Odd numbered Star Trek Movies haven't been mentioned yet, and frankly Star Trek V out-smells anything mentioned yet, including the Star Wars movies *and* the Highlander that shall not be named. Even Episode III (In which we find out the greatest bad guy in the history of fictional bad guys is basically a whiny 'lil shit.) failed to generate the amount of pain caused by Shatner attempting to direct.
I'm fine with him as an actor (Sure he was over the top - but dammit, Jim Kirk was over the top. I don't care what anyone says, in the time Picard took to say "Lets find common ground", James T. Kirk could shoot them, blow up their god, convince the evil AI to commit suicide, talk the downtrodden slave class into open rebellion, sleep with the gorgeous alien babe . . . *AND* walk away from the Prime Directive Court Martial review board smelling like a rose. Spock wasn't a loyal vulcan willing to lay down his life to save his captain and friends - he was just too damn curious about what was going to happen next to leave.), but dear lord, the man can't direct or write worth a damn . . .
