Giac, I too am a Tremors junkie. It is, as Peter pointed out, a fine example of male bonding, with a great indictment of the scientific community. The survivalists are portrayed as upstanding paranoid individualists. You can't find a better "B" film than this one.

The sequels are very poor and cannot be compared to the original though the third movie comes close. I recommend that you see the third and if you feel the need to watch something silly then take time to see the second one.
