this movie start out so great and really nail the fun and excitement of be a kid and want to build and explore with your friend . the first half of this movie be fantastic and especially when they decide to build a ship to put into the force field they have manage to create . they get bit and piece from a junk yard to create the ship and outfit it with gear and provision . they then do test run like any good scientist would before they decide it ready for a much big journey . it every kid dream and a ship that can take them anywhere they want to go . it such a great build up to an exciting adventure . but once they end up take the ship into space you might at as well turn it off . a complete shift in tone and intelligence . the final act of this movie be an enormous let down . still the first half be great fun . watch it again on dvd remind me of why i love and hat it so much a a kid .
