This is a great B-movie for people looking for a bit of a thrill.

At the very start of the movie you might think to yourself: "Why did they send an idiot with schizophrenic tendencies to the moon?". By the end of the movie you'll see exactly why this person was chosen.

If you can tolerate the numerous inaccuracies and mistakes the producer makes with regard to the conditions on the moon and in space, then this movie is very entertaining and I recommend watching it.

In this movie, madness jeopardizes a mission essential to humanity's survival. It shows how faulty logic hardwired into our brains can make our lives less effective and meaningful.

The movie gets a bit messy at the end and does a bit of cinematic mysticism which does not fit together with the rational message of the movie.

Overall, this is one of my favorite movies because not a lot of movies try to send this particular message.
