We all loved how Mike and Sally worked together, as well as their friendship in the "Monsters Inc". Now we get to see how they became to be such great friends and what were they like in college. The story begins with the first day of college, where we get to meet Mike Wazowski, who gets his voice from Billy Crystal, a little green one-eyed dude, who is anything but scary. He is almost invisible to others. On the other side of campus, there is James P. Sullivan, who borrows his voice from John Goodman, a classic student jock. So, we get the collision of two very different worlds as they get assigned to each other to practice for their practical exam. As Mike gets characterized as a geek and Sully as a sporty guy, they manage to do the impossible during the college games, spend their days in freezing environment after the things go wrong, manage to get back and still win the competition. But that doesn't end their miseries. This animated movie is great for the kids, at home, to keep their exes on the screen for a while and make them both laugh and teach a thing or two, but is also good for adults and lazy afternoon movie marathons. The director Dan Scanlon has made a great job.
