I definitely enjoyed, and recommend, this movie. As a long time Star Trek fan, I went in prepared not to enjoy it, but the movie delivered, staying true to the spirit of the original series, with none of the techno-babble and self-righteousness of the Next Generation.
The portrayal of the characters was good, showing how they developed into the older personalities of the original TV series.
Only one problem: I now have a Green Girl fantasy.....
