Just finished watching this tonight, the Matt Smith story that sees Amy separated from the Doctor and Rory, and time shenanigans mean that Amy ends up spending a very very long time trapped ...
This was my favourite episode of that year on first watch. It even beat Neil Gaiman's "The Doctor's Wife" for me. And I think I voted in the Hugos that year, when both stories were on the Best Dramatic Presentation (Short Form) shortlist. And I knew which I preferred, though the Gaiman story won the Hugo award in the end.
It's still powerful to rewatch today. The opening third is standard scifi setup, but when you meet the older version of Amy the emotional level escalates rapidly. I think I probably related to that more this time, because I'm closer in age to that version of Amy than I was when this first aired.
The direction is a joy, and one scene in particular stands out for me, when the two Amys - young and old - are able to talk to each other across time. Originally an older actress was intended to play older Amy, but Karen Gillan wanted to give it a go. And with the aid of prosthetic makeup does a fantastic job. By far her best acting in Doctor Who ever.
It's also remarkable as a low budget and Doctor lite episode. Matt Smith is very much in it, but the story is carried by Amy (both versions) and Rory, and both act superbly. I should also praise the writer Tom MacRae. I wasn't that keen on his Cybermen two-parter with David Tennant, but this - his other story - is stellar.
The ending is inevitable, but how you get there is in turns moving and shocking. And throughout so brilliantly acted.
This remains an absolute highlight for me of the Matt Smith era. There were some gems, even if there were some clunkers too.
