When the Enterprise is trekking around the galaxy, and the Rebel forces decide to bust out the ion cannon and fire it at the Enterprise's sorry ass, what do you think is gonna happen??? I'll tell you. It's bye-bye Enterprise, you're out of power, see ya later.
In all seriousness, I actually like both, for different reasons. Trek, at its best, be it in the theater or the small screen, gave you something to ponder. Star Wars gives you, at its best, thrills galore.
There are episodes of The Next Generation that rate with some of the best TV I've ever seen, I'm not kidding. And Wrath of Khan manages to give the viewer a little of everything....battles, revenge, pondering mortality, etc....
But, something like The Empire Strikes Back, which IMO is the best action film of all time, gives you more thrills than any Star Trek venture could hope to match.
Again, I like both, but if forced to choose which films I more enjoy, give me the Star Wars library over Star Trek.
