Breaking Down the Supergirl, Arrow, Flash, & Legends Crossover Teasers

By now you know the drill: a major movie or TV event comes around, and the trailers get scrutinized in painstaking detail.

It hasn't happened much yet with The CW's four-way Invasion! crossover, coming to your TV next week, for the simple fact that they've been remarkably stingy so far with the footage that's been released.

That's a double-edged sword, of course: it means that very few of the big moments are blown, but it also means it's hard for fans to get a handle on just what the story might be about or what to expect beyond "heroes vs. aliens."

Nevertheless, it seemed like with less than a week to go now before the cast of Supergirlmeets Cisco Ramon and the Maid of Might heads to Earth-1, it seemed like a decent time to look things over.

Also, at this point, we're not sure we'll see any more teasers until Monday!

So what are the handful of things we've noticed so far? And what might we have missed?
