It was alright. That's pretty high praise coming from someone who could never make it through a single episode of the old shows without cracking up and turning it off.
It was decent.
I never watched a single ep of any star trek seasons, so I had no clue what the hell I was getting into.
The cameo was pretty cool, though.
Having watched the entire TOS once, the entire TNG once, VOY twice, DS9 three times, a few episodes of ENT here and there, and all the movies at least once, I can say that I really liked it.
Although they did fuck up the story line because of time travel.
