In typical Pixar fashion, it's exceedingly clever and well-executed. The beautiful grounds of the school are lovingly rendered with great detail and an inimitable sense of atmosphere. You can practically feel the crispness of the on-campus air.
Last we saw Sulley and Mike, they were dealing with Boo, a human girl who they inadvertently brought to Monstropolis. This prequel doubles back to before the duo formed the best scaring team in all of Monsters Inc., though, back to when Sulley and Mike first met at school, where their contrasting sensibilities ensured they didn't become friends immediately. As the two slowly come to understand each other and form a real bond, they're involved in some Revenge of the Nerds-style shenanigans with their frat in a campus competition.

Dan Scanlon, who previously oversaw the Cars short Mater and the Ghostlight, directs the latest Pixar release. Once again, John Goodman and Billy Crystal voice James "Sulley" Sullivan and Mike Wazowski, with Steve Buscemi also returning as the reptilian Randall Boggs. The voice cast also includes Dave Foley, Julia Sweeney, Joel Murray, Peter Sohn, and John Ratzenberger, who presumably voices the Abominable Snowman again.
Monsters Inc. is currently playing in 3D across the nation, but Monsters University doesn't arrive in theaters until June 21st.
