Basicly; it's silly, exaggerated reenactments of strange, "real" ways people have died. Sometimes they even pull swerves and people don't die in the ways you might expect them to based on the setups.
I liked it, but it's my fourth favorite Anderson film (I think. I'd have to watch Tenenbaums again to be sure). I didn't care that much about the characters -- not nearly as much as I cared about Dignan and Max Fischer and Mr. Blume.
