Jump is not only hilarious and full of social satire, but the film craft is wonderful. Shaped, balanced, paced well, never too busy. Not to mention psychedelic. Pared down to the essentials, so it hits hard and big. Never got the widespread attention it deserved. One of the best of the time, or of now.
I saw it because the ad said it was made by the folk who made Joe, which was some serious and well-made stuff. And sure enough.
If you like Jump, or if don't, you should see Bliss (not the late 90's Hollywood fluff, but the mid 80's Australian movie-of-the-year). Bliss is one of my three favoritest movies ever.
