Signs was paced awfully slow (but the message was good), it is interesting to note that M. Night has said that he is interested in bringing back Bruce Willis for a sequel to the 'Unbreakable' pseudo/real life comic book series.
Yes Unbreakable was supposed to have a knock down drag out fight. If you look at the 2nd disc on the dvd he explains the reason why he cut the story. My teacher is on the disc.
