UPDATED after seeing the entire four-episode crossover series:
So far this week we've seen
I don't get it when they crossover characters in different TV shows. Back when The Flash visited Supergirl when it was back on CBS, both characters were portrayed as overly giddy, or more chipper than their normal portrayals.
And I'm seeing this same, completely out of place humor in this crossover event. I mean, look, "it's aliens here to kill us all. How cool is that?" Seriously? This ill-placed humor has made this a disappointing TV event on The CW. And this crap humor continued right on into the first third of the final episode of this crossover event.
The first episode on Monday, Supergirl, had nothing to do with the Invasion story line. It was an empty episode, so to speak, until Barry and Cisco showed up in the last minute of the episode.
The Invasion story really started in The Flash, where a lot of development and action took place there.
