I thoroughly enjoyed this movie although it has an invasion of the body snatchers feel it is also different in some ways with a kid being the main character the adults don't believe him but the kid is friends with people in the town because his father is a good man and the movie sets this up so that when he is being controlled you can tell something is wrong. Unlike the invasion of the body snatchers wherein there is a definite good ending this movie has a more unclear ending which I won't spoil, overall with the effects the sand effects are great, the main alien's effects are good, but the minion's effects are OK. So this movie is a good watch and while not as good as the invasion of the body snatchers it is still worth it to watch both.
