Your love of it will largely depend on how funny you find a movie with 85 percent of the jokes based on smoking weed. For the rest of you a lot of it is going to feel very silly, crammed with potty humor and overly long for such a simple subject matter.
The first half-hour floats by on a cloud of mildly funny lines ("couscous - the food so nice they named it twice"), but then slumps into a derivative action caper that's weirdly and unappealingly reminiscent of Eighties dross like Beverly Hills Cop.
The Freaks And Geeks boys prove that weedy action men are where it's at. Pineapple Express sometimes zones out but mostly blows minds and inspires some delirious giggles. Like the titular grass, really.
