You hear it in lots of (usually sad) movies, and I'd say it's probably one of the truest things ever spoken: "There's nothing more tragic than having to bury your own child." But, just for the sake of argument, let's pretend -- for just a second -- that (in one specific case) it wouldn't be the end of the world. As a matter of fact, let's further pretend that the death of a child could somehow lead to several wonderful and life-changing results.

Sick, I know, but that's one of the ideas that runs through the twisted-yet-amusing dark comedy World's Greatest Dad. Written and directed by the consistently unpredictable Bob Goldthwait (he also gave us the similarly strange Shakes the Clown and Stay), and anchored by an unexpectedly strong Robin Williams performance, World's Greatest Dad is indeed about a high school poetry teacher who finds his life blossoming after his son accidentally commits suicide.
