Oh man oh man. This just isn't your day. You managed to miss the whole fundamental reason why the whole movie actually existed?
Small recommendation: first read the whole thread, then hit reply if still necessary. (And no, mixing up Vulcan and Romulan when reading a sentence on the internet doesn't necessarily mean missing the whole fundamental reason for why the whole movie actually existed, which in turn has nothing to do with being the prime motivation of Eric Bana's character)
He's JJ he doesn't need no stinking plot. Sugar baby, its all about the sugar.
Except he does, he just doesn't care enough for it to be a good one. I'd have admired him a tonne if he'd actually managed to pull off this movie without a plot altogether!
