John C. Reilly is the big star of this movie. Everyone else is supporting. This is a must see in 3D movie to appreciate the special effects which are right on par with what is expected these days. There isn't a lot of character development like The Jackson Kong but there is more action and it is nearly non-stop. If you just want to be entertained and forgot about your problems for two hours then this is a good movie to see. Enjoy.
