The reviews are lukewarm at best and cool for the most part: not one critic recommends Old School outright, and most place it somewhere between harmless and unfunny. Most reviews measure it against Animal House and find it the tamer copy. Where praise exists, it lands on the two leads. Vince Vaughn is repeatedly picked out as the reliable source of laughs, and Will Ferrell’s compulsive nudist earns a grudging chuckle even from critics who dislike the rest.
The complaints cluster on structure. Several reviews find a promising first half that runs out of ideas, with sub-plots left hanging and an ending that backs away from the misbehaviour it has spent an hour celebrating; The AV Club adds that the editing leaves it feeling unfinished. The spread is narrow, from mild approval to flat dismissal, with Radio Times the warmest voice and Eye for Film the harshest, extending its objections to the leads themselves and calling Vaughn wasted.
