Eventually I'd like to do a review for every series, but since series six is fresh in my mind, I thought starting in the middle is better than not starting at all. So prepare yourself for Doctor Who awesome-ness!
Just a precaution: there will be plenty of spoilers ahead!
Series 6 is by far the most complected series so far. Lots of tie ins and we finally get all the details about River Song's past. I've been waiting for that since Silence in the Library/Forest of the Dead!
The main alien/bad guys were the Silence. They remind me of the classic 1960's styled aliens, even more so since they wear suits. Surprisingly there weren't many of the typical DW aliens this season. There were some Cybermen in an episode, but the weren't nearly as threatening as in the past. We saw an Ood in one episode and a Dalek for a brief moment in another, but that was about it.
Closing Time was probably my favorite. I love ho the Doctor speaks baby and was talking with Alfie. Or Stormegeddon as he likes to be called. It was just a really fun episode with so many memorable parts.
Amy Pond, the girl who waited. I really wasn't a fan of her in series 5, I felt like she pushed the Doctor around a bit. But after she and Rory got married I began to like her a lot more. It's hard not to feel sad for her considering how long she waited for the Doctor the first time and how many times afterwards that he say's he'll visit soon and it's years later. In series 5 I didn't seem like Amy really appreciated Rory, but I feel like she does a lot more this season.
The Last Centurion, a.k.a. Rory Williams. He's awesome. He's always loved Amy and would do anything for her. After all, he waited over 2,000 years for her. Rory just goes with the flow no matter what is happening. I love how he always asks the logical/practical questions.
I'll admit, after watching The Impossible Astronaut and Day of the Moon I had to look up who the young girl who regenerated was. I nearly screeched with excitement (I refrained since it was late at night) and was practically jumping up and down when I found out she was River, who is the Pond's daughter.
It's weird when you think about it. Amy and Rory named their daughter Melody, after their friend Mels. But Mel was their daughter, so not only did they grow up with her as their friend, but the named their child after their child. Time travel is complected stuff, folks.
