How bad is it? It somehow manages to rip off both Alien and E.T.
Should you see it? It's weird, but not quite weird enough.
This has decent sets and special effects, but the plot just jumps from one thread to another. Astronauts find a crystal on Mars and try to bring it home, but they get trapped on a shuttlecraft with an alien that comes from the rock. There's a tentacled monster and drained corpses and nothing new... until... the alien invades the ship's computer system, uploads the Bible, gets religion (!) and turns into a benevolent alien. Then the movie becomes an E.T. retread.
