I saw this in a members' preview at the wonderful Bryn Mawr Film Institute.
I truly enjoyed this movie. It was smart, hilarious, well-acted (especially Downey, Yelchin, and Davis), and well-scripted. I definitely recommend it, but not with the type of superlatives that other commenters have used here.
If my regard for this movie fades over the coming days, it will be in part because it's so easy to write a "recipe" for the film: it's 3 parts Pump Up the Volume, 1 part Rushmore, a generous dollop of closure, and enough cuteness and sweetness to smooth all the potential edginess out of the subject matter. Unfortunately, it's the sweetness that renders this movie inferior to both of those earlier movies (which are excellent). Once I was struck by the Pump Up the Volume comparison, I couldn't shake it, and I kept thinking that, although it has not aged wonderfully, Pump Up the Volume was the more honest and hard-hitting movie, and Rushmore was simply better.
