This movie is far from great, and feels, and looks exactly like a TV movie. The movie was made for Sci-Fi and looks it, but is still somewhat more interesting then the other dreck I've seen coming out of that channel. If you are going to watch Species 3, get the R rated or Unrated cuts. Don't bother with the TV version. The parts of this movie that are interesting are the extreme violence, and the almost non-stop nudity and sex. I'm not joking. The second Sara, the new alien, matures she is naked for a good twenty minutes. The story itself is entertaining, and the cast is good, although it does seem that everyone really would rather be doing something else, with the exception of Robin Dunne as the lead male, the guy who played his roommate, and Sunny Mabre and the girl who played Amelia. So basically, the younger twenty-something cast did well, while the older actors seemed to phone it in.
The effects are decent, with some great gore moments, and the creatures, while cheesy as can be, fit in with the film very well. The action is a little hokey, but over all, it works.
I saw the R-rated cut, and while all the violence was intact, there is about one minute more of nudity in the unrated cut. How there could be more, I have no idea, because the Sara and Amelia's breasts are on display for a good portion of the films running time. If you want a cheesy, but entertaining B-grade Sci Fi flick, there are worse things you can get, although I would suggest getting the first movie instead. But if you've already seen Species 1 and 2, check out part 3. I do think they would have been better off doing a TV series than this movie, but either way, I have a feeling that if this does alright we will probably end up with a Species 4.
