The first thing I learned about Monsters vs. Aliens is that it is 3D. Thanks to booking our tickets on the internet, we were without 3D glasses when the film started. We got that one sorted quickly.
Monsters vs. Aliens is a simple story. Susan (Reese Witherspoon), soon to be married to Derek, is hit by a meteorite whose special powers turn her into a giant woman. She is quickly isolated by the government, and sent to live with other captured 'Monsters', the blob Bob (Seth Rogen), the lizard man Link (Will Arnett), Dr. Cockroach (Hugh Laurie) and Insectosaurus. However, she has a battle on her hands when the evil alien Gallaxhar turns up on Earth to reclaim her super strength.
There were several families in the cinema and it was clear that the kids were enjoying this film. What was even more apparant was that the parents were enjoying it too. It's full of obvious humour as well as multiple references to the great alien invasion films of the past. There is more than plenty to keeps adults amused. The character of the U.S. president alone is worth the entry price. Reese Witherspoon voices the character of Susan (or Ginormica) with flair, and she is truly a fabulous role model (with great catsuits) for the younger female viewers. Watch out for Kiefer Sutherland in the role of the monster's keeper, General W. R. Monger.
I pretty much laughed my whole way through Monsters vs. Aliens and left the cinema in a very happy mood. I hope that it does the same for you.
