I liked the finale
This hasn't been the strongest season of the show but it has had some great episodes sprinkled in (my personal favorite being the blind spot). The finale was pretty good: taco mysteriously disappeared, Ruxin got to meet future Ruxin played by Larry David, Pete finally won the sacko (something I've been hoping for every season) and of course a final appearance from Shiva.
I'm sorry if you felt the finale wasn't up to par, I know the feeling of loving a show and hating the finale and no ones differing opinion can make that better.
