I left Nemesis thinking, "Man, that was disappointing."
I left Star Trek '09 thinking, "That was awesome!"
And yet...somehow...I still manage to enjoy lots of other Star Trek shows and movies. It's just crazy how that works out!
I like the ST09 better than Nemesis because Nemesis sucked balls. It has nothing to do with whether one of those movies is more true to the spirit of Star Trek than the other. ST09 is simply more entertaining.
