The hedonism on display is very much of a piece with “Trash Humpers” and “Spring Breakers,” but in a surprising change of pace for Korine, the film is more at ease with itself, and more emotional than either of those two provocative efforts.

Joyous, outrageous and slyly mournful.

Korine’s visual gifts are on full display, capturing both the opulence of Florida and its scuzzy side in a way that finds beauty in both.

[McConaughey]’s so entertaining, in fact, that it takes nearly the entirety of “The Beach Bum” to fully absorb how little else there is to the film once the initial high of basking in Moondog’s perma-stoned glory wears off.

The Beach Bum is a skillfully crafted and often hilariously entertaining, but like an evening with Moondog, it might leave you with a hangover.
