The best of the movie, which tacks on a spring-break climax filmed in Puerto Rico, works incrementally and off-the-plot, paying its biggest dividends the closer it sticks to the college dorm. Across the hall from Jenko and Schmidt, there's another brother act, this one with real brothers: the hilarious identical twins and comedians Kenny and Keith Lucas, who treat the movie to a "jinx, you owe me a Coke" routine that is truly wonderful. (I could've watched these two all night.) A frat-house break-in becomes a string of lovely, stupid bits contrasting Jenko's reckless stupidity with Schmidt's safety-first ethos. Be sure to hang around for the closing credits, which imagine all sorts of "Jump Street" sequels to come, all of which look funnier than "A Million Ways to Die in the West."
