I watched this movie tonight in 2-D and can't for the life of me figure out why it's only rated 5.1/10 at IMDb.com. It has a fun story, good characterizations and great animation with possibly the most realistic motion-capture character ever in Gribble, the childlike adult victim of the Martians' earlier Earthian foray. I'll admit that it may possibly be perceived by some as portraying radical feminism in a bad light, especially with the faceless Storm Trooper uniforms of the Martian guards and their Hitleresque female leader, the Supervisor. Perhaps one reason for the negativity is the absence of cute cuddly animals like in practically every other Disney animated movie, but there was the robotic Wingnut in a very limited presence for the die-hard cute animal enthusiasts. The only other reason I can see for all the negativity is that Martian women are portrayed as intrinsically incapable of raising children on their own without male help and must solicit "instructions" from a "real woman." I give it a 7/10.
