The Doctor: You're thinking of stopping, aren't you? You and Rory.
Amy Pond: No, no - I mean, we haven't made a decision...
The Doctor: But you're considering it.
Amy Pond: Maybe. I don't know. We don't know. Well, our lives have changed so much. There was a time, there were years when I couldn't live without you. Um, when just the whole every day thing would drive me crazy. But since you dropped us back here, since you gave us this hiatus, you know, we've built a life. And I don't know if we can have both.

The Power of Three Review
22 September 2012 | by (Sweden) – See all my reviews

I had high hopes for this episode mainly because of the writer, Chris Chibnall proved with Dinosaurs on a Spaceship that he truly understands what Doctor Who is about and wrote the Best Episode since The Girl Who Waited last year. The Power of Three did look like a more proper Doctor Who episode (Dinosaurs was more there for the sheer fun of it) so it was interesting to see Chris write that in a blockbuster style. Ironically this is the least blockbustery episode this Season has had so far but I have to say it is (almost by far) the best. Everything came together in spectacular fashion. The directing is almost as good as Asylum of the Daleks, the writing is the best this season has showed so far, the acting has been improved since last week... just wow.

I Really tried to be critical of it while watching but I just couldn't cause it had everything I wanted it to have, Brian Williams was an amazing character this time again turning out to be my favorite companion parent ever so it's sad that this is going to be his last episode since the Ponds are departuring next week but it's great to see he left in an amazing episode. This episode truly was amazing and i'm shocked that I am saying that because you don't get to say that often.

Of course there are a few minor problems with it but I don't think they should have been fixed (like how Brian was able to do a daily log of the cubes for over 300 days or how Brian could watch the Cube for 4-5 days after the Doctor left him in the TARDIS) but it all added to the mystery of them and didn't really distract me from the story. The episode kinda felt like it was written in the RTD era of the show because of how much the cubes was on the news and how it felt like it was the end of the world. Hopefully every writer of the show will look at Chris' episodes this season and be inspired so we can continue to have amazing stories like Dinosaurs on a Spaceship and The Power of Three in the future.

Quick Next Time Trailer Review - REALLY excited, The Ponds final chapter looks like an ending they deserve on the most impressive companion journey I have ever seen on Doctor Who.
