Q the Winged Serpent. Michael Moriarty's character was kind of a scumbag... and his performance and the writing made me care about him and even agree with a lot of what he was saying. Excellent character motivation. Damn fine socio-political commentary too (and very ahead of its' time: Rupert Murdoch name-drop). Also, I loved the monster, the camerawork was great, and it was unpredictable in all the best ways.
Candy Clark worked my last nerve though.
