Definitely Excellent Adventure - loosely, our heroes find themselves arrested, and unable to go and present their report, before realising that they can escape using a number of elaborately pre-arranged things that appear as soon as they mention them, as long as they remember to go back in time and set them up afterwards once they've escaped. (Most notably some keys that were already established, in passing, as being missing at the beginning of the film - because, as it turned out, Ted had travelled back in time and stolen them - which fried my ten-year-old brain at the time, I concocted some sort of explanation about us the viewers not seeing the "first pass" through the timeline, when the keys weren't missing, but rather the altered time "re-run" or something. Unbelievably, I didn't notice the similarity with Who until it was pointed out to me.)

I wholeheartedly approve of the use of time travel gadgetry for plot advancement, I'm a sucker for time travel stories generally. (This was the first rollicking one I've seen since Bender's Big Score.) My favourite thing about the whole episode, though, and cementing how much I heart the Eleventh Doctor, was still Smith's delivery of "I wear a fez now", for which he should receive a knighthood.
