"Star Trek Into Darkness" is fun. It's a muscular, rousing piece of summer entertainment of the sort that J.J. Abrams has mastered.
I find it almost impossible to say more without spoiling the myriad of plot surprises built into its plot. Others apparently aren't having this difficulty, so feel free to read them if you're spoiler-phobic.
Believe me, this movie has surprises.
So seriously, if you don't want to have your surprises stolen, stop reading. I'm not talking about a spoiler here or a spoiler there. I'm going to spoil the whole darn thing, right till the end. Might as well go whole hog here.
This is your last chance.
