Just watched the first part of the finale. Holy shiiiiiiiiiiiiiiiiiiiiit
So many theories buzzing around my head aaaa. Anyway, what Moffat did to Rory was horrible, I felt so sorry for him although it was really nice to see him again in all his supreme Rory-ness. They pretty much had me at the intro, I really liked that sequence, the 'hello sweetie' was absolutely awesome. Speaking of which, River was cool than usual in this episode and played a pretty major part in it. (Dat big reveal(never saw it coming))
The Doctor's big speech was pretty damn good and so was the concept of from everyone else's perspective, the Doctor is the villain and they are doing the right thing. Amy totally isn't gonna stay dead though and they won't kill off River (vortex manipulator up in this bitch)
Overall, it was totally win. I'm really pumped for the proper finale. (Also, my money's on that voice being the Doctor after he comes out of the Pandorica. (The brakes being left on when the tardis is being hijacked seems to point towards it for me))
