You're not alone in that that's why it was good that another Doctor is coming to liven things up again. I hate to admit it but there were just more meh eps this past season. They build it up so much, like the monsters, and they don't live up to the expectations. I'm just glad Matt's quality of acting always rises above the writing; he never disappoints. I hope having a different showrunner with Moffat will shake things up as well. I do think with Matt's departure, some of those that were into the show because of him might leave as well. That's okay to me though. Diehards die hard, you know?
