This is a found footage flick with a cute idea. That there was one more Apollo mission than history allows for. Suddenly we have all this footage found (no doubt from some secret archive), of the last mission. As you can guess it doesn't go well. Though seemingly routine at first, things get bad as our brave astronauts find dead Russians and stranger things on the moon.
On the one hand the tight claustrophobic sets of the landers add a sense of terror. Also as with any of these movies there are scenes that will make you jump despite your best interest. However, the net effect is less than impressive. In fact, it was pretty durn slow in spots. Also, the science nerd in me was left to wonder what did these monsters do wheh there weren't astronauts to snack on. There's no sense of an ecology or a natural order to things. I'm more likely to accept demons than poorly thought out "natural" creatures. That's just me.
Still, this is a decent little chiller and by the standards of most horror films slightly above standard.
