Longmire improves dramatically once you get past the A&E seasons to the first Netflix season. I'm only one episode into the latest season, but it's shaping up to be the best so far.
It's becoming too much about the main characters, there's little detective work, it's too connected (I'm getting lost, especially with story arcs-spanning seasons), and it's too much about the main characters self-destructive tendencies rather than compelling whodunnits.
Luke Cage took my attention away (he's dreamy), but I'm a few episodes into the new Longmire season now. It looks like they're trying to get back to the crime drama premise of the show.
