I have to say that this show really exceeded my expectations this season. The early episodes may not have been as impressive, but the Darth Maul Story arc and the conspiracy to end the season really impressed me as some damn good story writing. I can't wait for the next season, hopefully Disney will allow the writers to take the next step.
The finale was perhaps one of the top episodes of the series. You could feel the tension between ahsoka, the Jedi, etc. And I did not expect her to leave the order, and despite my allegations against her early on, it was a really emotional scene between Anakin and Ahsoka. If this show ended on that note, I'd be fine with that. A great ending.
