New York Times:
National Lampoon's Animal House is by no means one long howl, but it's often very funny, with gags that are effective in a dependable, all-purpose way.
While the low comedy is undeniably effective, the film leaves behind a bad taste of snobbery and petty meanness.
The movie is vulgar, raunchy, ribald, and occasionally scatological. It is also the funniest comedy since Mel Brooks made The Producers.
The Lampoon people understand the darkest secret of an American college education: one of the noblest reasons to go is to spend four years studying sex.
An unashamed sense of its own fantasy is coupled with classically mounted slapstick; nostalgia mixes with cynicism in seductive proportions; and John Belushi's central performance as brain-damaged slob-cum-Thief of Baghdad is wonderful.
There's enough bite and bawdiness to provide lots of smiles and several broad guffaws.
You may not care to take up permanent spiritual residence at Animal House, but it's funny place to visit.
