Didn't watch it yet. Let me know if it's a good movie.
Of Gods and Men was a very engrossing movie. With so many original Star Trek cast members, the main thing that it lacked was first class special effects. I would say that the special effects were on a level about equal to the earliest Babylon 5 series. Definitely worth watching, especially since it was free!
As far as other Star Trek movies online, there is a Star Trek channel on YouTube.

I watched one of the movies (Star Trek Hidden Frontier: Operation Beta Shield), and it was interesting, though none of the cast were original cast members from the TV series. I think that movie is the beginning of a series, but I am not sure where it fits in with the other "Star Trek Hidden Frontier" videos on YouTube. The special effects were in some ways better than in Of Gods and Men, though the acting and the script could have been better.
I'll have to check out Star Wreck: In the Pirkinning as soon as I can find it.
