May cuts deep into the festering resentments in a lifelong friendship between two now middle aged men. There’s a lot of emotional rawness here that surfaces with visceral power, but it seems more like the product of actorly expressiveness and improvisation and less like the design of a particularly deft script. After a while it gets a bit wearying, and the wholesale crappiness of at least one of this pair just makes you look forward to some mercilless dramatic justice. The vérité cinematography is gorgeous.
