AVclub actually watched the whole thing and did a write-up on it today.

The strangest thing that I got from the article (other than the fact that the robot had a conversation with a mosquito) is that all the bad, fan film-quality CGI was actually done by the Stan Winston Studios and ILM. If this thing wasn't three hours long, I might actually consider renting it when it came out here.
