SEASON PREMIERE: Season 4 of this comedy series picks up after the disastrous cliffhanger that ended Season 3, when Jimmy (Chris Geere) proposed to Gretchen (Aya Cash) – and then walked away, immediately and without explanation. The new season begins with both characters reeling in the aftermath – she’s wondering why he proposed then fled, while he’s hiding from life in general, and her in particular, by living in a retirement-village trailer park. And that’s where Season 4 begins… For a full review, see David Hinckley's All Along the Watchtower.
