I've seen The Impossible Astronaut about 9 times now, each time loving it more and I am now utterly convinced that we are witnessing the adventures of the best TARDIS crew that we have ever had. The chemistry between all four crew members is mind-blowing. In decades to come this crew will be ranked up there with the likes of the Second Doctor, Jamie and Zoe.
Series Five was great for chemistry too, no question about that, but there was a sense of "special guest star" about both Alex and Arthur. This time, however, both are well and truly the Doctor's companions.
Rory is my favourite companion in 'New Who' and it seems that he will remain so for the foreseeable future. His clever mix of lovable but clumsy and brave and capable is what makes this ordinary, ordinary man so extraordinary. Played with the perfect balance of humour and heart by Arthur Darvill, Rory is - as we saw during the Doctor's funeral scene last weekend - more than up the the job of taking control of the situation in the Doctor's absence, but knows that when the Doctor is about he is an assistant only. There's no bitterness there. Sure, there's some jealousy over Amy, but when it comes to the crunch Rory is the Doctor's fiercest friend.
This entire crew compliment each other perfectly and I hope to see them travel space and time for many years to come! I fear, however, that this may not turn out to be the case. I have a terrible feeling that Amy and Rory will be leaving us - based on nothing, this isn't a spoiler, just a hunch - and if they do, I will be sad to see them leave. So, here's to the best crew the TARDIS ever had. The Eleventh Doctor, Amy Pond, Rory Williams and River Song. Awesome. Just awesome!
