Saw the Flash crossover episode of Supergirl last night, think it worked pretty well, a fairly good teamup that somehow avoided the trite "they fight before they team up" trope. They worked together really well, it's just a shame that they've set the series in different universes so it's presumably a one-off.

Anyone else catch it?

I did, and I thoroughly enjoyed it. They seemed to me to hit all the right notes and they definitely left me hoping for another crossover some time in the future.

I watched it. Cute.

With Supergirl leaving CBS and moving to the CW another crossover is definitely possible. Those two have a great chemistry!

Someone on another forum suggested that they might merge the universes in some sort of "crisis" event to make crossovers easier, possibly as a result of all of the messing about with time in Legends of Tomorrow. It'd be cool if they could make it work.
