It was a surprise, a very pleasant surprise. This movie was much better than I thought it would be. I know going to see a Marvel Studios film I would be getting a well crafted film but this film was good, it was funny without being silly, it tweaks the normal scifi hero stereotypes and story lines, it pokes fun at itself. I knew that there would be some quirky characters such as Rocket Raccoon and Groot and thought how cute some interesting but secondary characters. However Rocket and Groot are the best part of the film, they make the film and are the most interesting characters in the film. Luv them.
Yes, go see the film, it's great for kids, and for adults. It has a great sense of humor and with the soundtrack you will laugh throughout the film. I do think that Guardians of the Galaxy will become the blockbuster film of 2014.
