The 2012 comic reboot of teen cop series "21 Jump Street" worked almost entirely thanks to the efforts of its game cast (Jonah Hill and Channing Tatum, chiefly). The simple script and low-impact direction certainly didn't add much to the proceedings. This rude follow-up (set in college) tries a little harder, crafting a bigger-stakes story and a perfect storm of self-mocking jokes. It ain't smart, but it does have drug content, brief nudity and a Benny Hill reference. Also, it's been shoved back into theaters for a week so it can make more money. 112 minutes R.
