Query: Alien Guys with Big Heads

This film is unbelievable. It brings the audience all the way to the end of the film and then the filmmakers really don't have an ending. You essentially get another ARTIFICIAL INTELLIGENCE type ending, which has been used too many times now. After seeing MISSION TO MARS I can now appreciate a film like EVENT HORIZON which chose a graphically violent alternative but dared to be different and challenge the viewer.
