I saw this yesterday in a cinema in New Cairo, Egypt.
Paul Wilson as Dr. Van Hook was the best live action cartoon villain ever! And made up all of the movie's funny moments. Without him, it'd be a 1 star. His henchman also did a great job, and the best parts of the movie are the two of them interacting hillariously.
The others acting was very subpar, except for the henchman, who was great.
R. A. D. A. R. Became a legit Mary Sue. Every time, the dog had some additional supermanesque power be revealed, solving every problem easily and without effort, including a really stupid stunt in the end.
