It was free, so I did not expect much in terms of production value, but I was pleasantly surprised by a decent story. I was very iffy about watching it in the first few minutes, because I spotted a lot of annoyances, including the fact that the player was pressing both the trigger and the 'a' button while they only shot in Halo. They should be jumping rapidly, too!
Anyway, this was a good movie, and I loved the concept behind it. It is a little bit The Matrix and a little bit Total Recall. It has a lot of replay value. Ha, see what I did there? Watch this movie, but once you watch it, you can't stop. Okay, you can, but only once you beat it.
