Sluggish, but Satisfactory
The entire film moved at a snail's pace, which is my biggest gripe. I do understand that this is a horror film, and slowing things down in a dark environment can really add suspense and anxiety. However, what you have here is called "overkill," especially in the first several scenes where you show static images of the desert. Completely unnecessary. Each one of those should have only lasted a few seconds, not 20.
BUT, you managed to demonstrate PERFECT timing in two scenes. The first would be the scene when the alien opens his eyes. You left his eyes closed just long enough for us to start second-guessing ourselves, sort of like: "oh yup, the alien's about to open his eyes ... wait, is he? ... OH SHIT!" That was fantastic, because it really added a little shock to the moment (especially since the eyes were drawn so well). Even better was the last scene of the movie, where we got a first-person of the guard in the facility. Again, you dragged it out just long enough for us to think, "well, maybe something isn't gonna happen just yet" and then WHAM! Crazed mutant guy drops from the ceiling with a shrill growl and glowing eyes. Excellent.
Overall, this flash was definitely good, but the horrid pacing substantially detracted from its quality. This could have easily been an 8 or 9, but simply put, I was bored more often than scared. Nonetheless, the graphics were outstanding, and the animation certainly had that B movie vibe. Good work.
