Most of us who watch Sci-Fi do turn off our brains.
I mean none of us actually believe that Superman or Spiderman or X-Men or Hulk, etc., exist. We turn off our brains. That is the only reason we are able to love Sci-Fi in the first place.
I we did not like Star Wars, Star Trek, Lord of The Rings, etc., because they were REAL. We turned off our brains.
I love monster movies (Godzilla, Reign of Fire, LORT, SW, etc.). Most of them DO NOT have great plots. But they are not too retarded.
But who the heck would be holding on to a damn camcorder with dear life when monsters are killing everyone? It's retarded.
Get rid of the camcorder, and the movie would not be as bad!
Oh, and you want to save your girlfriend's life and risk your life in the process? Hey, that's cool. I hardly know you. But I will risk my own life and follow you to the end! I will die for you and your girlfriend!
