As far as a finale goes - it was good. Wasn’t awesome or epic like ‘Six Feet Under’ or ‘Breaking Bad.’ Wasn’t terrible or disappointing like ‘The X-Files’ or ‘Dexter.’ It was much like the show had been, more of the same. Nothing wrong with that at all.
I won’t miss it as it overstayed its welcome four seasons ago, but it’s nice to see a show find a decent enough closure (which is rare). Wish Alan Ball wrote/directed the finale. That would have been more fitting.
