Effects: Superlative. And, they never really get in the way of anything which is quite impressive.
Story: Believable/Plausible, especially considering Trek's historical reliance on time travel.
Quality: WWAAYY above most previous Trek movies. The Wrath of Khan is still better, but not by much. However, the music score, while adequate, doesn't really do the story justice.
Redshirts Killed: 1. C'mon -- EVERY worthy Trek episode has to kill at least one. His death is quite spectacular, or not, depending on your point of view.
Overall value: $9.50 out of $10. A stellar movie, no pun intended.
