Jacobs has found a way to play that character in such a way that Mickey is endlessly surprising rather than easily irritating. ... Gus has always been just as deeply screwed up as Mickey is. In this final season of the show, there’s a reckoning with his own neurotic behavior, and Rust shows himself fully up to this challenge as an actor. Love also delves more deeply into its supporting cast.
Rust, Apatow, and the other writers make an understandable attempt at supporting character development this season, which takes some of the weight off of the main couple, but it's the surprising chemistry between Gus and Mickey in both love and war where Love thrives.
To its credit, Love manages to close on its own terms, on an unconventionally hopeful note. But it also provides something that most of us seek but don’t often find from our television shows: a couple of genuine surprises we didn’t see coming.
