Let's start with the the special effects, these are cross between Jerry Anderson's, UFO and Babylon 5. You can really tell that it is mainly CGI green screen and very little in terms of physical sets. When they do use physical sets you can see things like the car switches and even recycle symbols and the bottom of walls. So don't expect Star wars effects but they are OK. The acting is pretty wooden, but the actors try their best and keep the story moving forward at quite a nice pace. It is watchable for the 90 minutes it lasts. I think they could have made more of the girls story line which added a nice twist.
Obviously the amount of budget they had to make this movie was pretty small but they made the best of it and I definitely think it is worth a watch.
