It was Rip Hunter that really sold me on this show. Its Rory Williams as a time traveling hero! Think of all the possible Doctor Who/superhero cross overs that could be done!
Doctor: Rory, I'm going to need to drop you off for a bit in America. There are these.. people... meta human people that I heed you to keep an eye on and get them focused on a common goal.
Rory: Well why me? What sort of goal, what do I need to get them to do and where will you be?
Doctor: they need to work together and I need someone there to make sure they make they leap off the perverbial cliff when the time comes.
Rory: how am I supposed to get them to jump off a cliff. And you still haven,t said where you'll be.
Doctor: its a metaphorical cliff, Rory, try to keep up.
Rory: and what am I supposed to do, just walk up to them and go, Hello, I'm Rory Williams from east London... ?
Doctor: well yes... no..I suppose you could use a better name, something tough sounding that will demand respect. Like Rip. That makes you sound tough, that you could rip things...
Rory: Rip? Who calls anyone Rip?
Doctor: yeah, Rip... Rip Hunter that will make you seem all... huntery. That's cool right?
Rory: that's the silliest name I've ever heard of....
Doctor: and say you're from the future... they'll Iike that, being from the future is always cool..... maybe you should wear a bowtie
Rory: you still haven't told me where you'll be..
Doctor: I'll be the one setting up the cliff.
Now that'd be something I'd want to watch.
