I thought this "season" has been not as awesome as previous seasons. I like that they have been showing different sides of the doctor and making him even outwardly doubt himself. Just some of the episodes haven't really been as intense as the last two seasons.
This season has been a mini farewell tour for Amy and Rory so far. They're exploring new territory about how The Doctor affects peoples' real lives. This is the first time he's been SOOO involved with a companion for so long. I think it's pretty interesting.
As for the excitement factor - That should ramp up considerably this episode with the angels coming back. I'm also a River Song fan (many are not) - so this one has that coming as well.
I'm very curious as to how they are going to introduce the new companion over Christmas... Will it somehow actually be Oswin? or just the same actress...
Should be a roller coaster with a brand new arc after the break.
