My friends and I noticed how similar he was to Ten, very noticeable. Especially in the bit he had directly at the end of EoT when he did the whole WOOHOO thing and lifted his leg on the TARDIS. However, there were the little bits of Eleven in there and these increased until the end where I think he was in his own. I just assumed it was because he was thrust into everything straight after regeneration and it was Moff's clever way of ebbing away the old and replacing with the new. The whole conversation with Amy in the console at the end...that wasn't Ten. I can't imagine David doing any of that, nor Ten speaking those lines. I guess we have to wait and see.
Also agree that there were some disturbing themes in this episode - yeah, let's teach kids to invite strange men into their houses and cook for them, letting them tear apart your kitchen. Also, poor Amelia left on her own and then growing up to be a kissogram? Was the kissogram part necesary? I know he wanted to show she was messed up but...I dunno, I think there were plenty more subtle ways to do that in a kid's programme. And Moff has kids!
I think that's ultimately what the epside was lacking. Subtlety. There were some wonderful parts ofc, like the actual dialogue between Amelia/Amy and Eleven and the one-liners I've come to know and love Moff for, and I took the harks back to his previous episodes as homages, introducing the series again with something familiar to ease transition, but the design of the spaceship and the alien in it's true form were not well thought through and seemed obvious, sloppy and forgetful. Because really, they were secondary to an already thick plot surrounding Amy and Eleven's relationship.
Still, good episdoe all in all. I just hope either Moffat writes more 'Blinks' or at least matches RTD's greatness cos there are already too many fans that think RTD was TERRIBLE and the sun shines out of Moff's backside and I'd hate to see such fans rebel and be disappointed yet again...they can get vicious.
