I watched Star Trek a couple of days ago.
I had the feeling that this movie would beat Xmen Origins in a previous post
The verdict: simple plot, amaingly and beautifully science fiction movie. From the begining and without any introduction you are deep into the story line.
I liked the way each character has been introduced and showed its development, keeping in the back of my head how these character later (in the original series) became the way all Star Trek fans know
I read somewhere that there is a follow up to this prequal, something I certainly looking forward to.
If you don't like Star Trek, its still a great action packed science fiction movie. If you are a Star Trek fan, this movie is full of things that make you smile and enjoy.
