Some of the other reviews summarize this pretty well. The Mosquito Coast details flawlessly the grotesque decomposition of a good and true man. Harrison Ford's Allie is driven insane by his own intelligence and inability to control his ego. Even more remarkable and disquieting is the fact that this is based on a true story. In some ways, Allie reminds me of Dr. Mobius from Forbidden Planet. But the demons Allie conjures up are far more grotesque and deadly than anything from even Mobius' warped imagination. I conclude that this is a true piece of art and science -- magnificently crafted from beginning to end -- and I will NEVER voluntarily watch it again.
