Guardians of the Galaxy was a huge risk. It’s adapted from a comic book that mainstream audiences are completely unfamiliar with, there’s relatively little star power in the cast, and two of the main characters are a talking tree and a sassy racoon. In the wrong hands, it would have been so easy for this to flop with Marvel fans. But despite all odds, Guardians of the Galaxy is the most fun summer blockbuster I’ve seen in a very long time. This is without a doubt the best Marvel Studios movie so far.
