I think this movie suffered from a misleading ad campaign which made it look like a slapstick comedy. It's not.
It's adult comedy-drama, and a pretty good one. Crystal, the ultimate cynic, slowly becomes best friends with his giant, the ultimate innocent. And there are actually a fair amount of laughs along the way.
It helps to know that this picture was inspired by the late Andre the Giant, who worked with Crystal on "The Princess Bride." Giants' lives are never easy, and that's why this picture has to be serious as well as fun.
I have the feeling this picture may play better on video. If you like funny-sad pictures, check it out.
