Kind of a slow start for what was billed as a big crossover event. Reasonably entertaining, but I was hoping to see Ray pass the torch to Ryan Choi. I hope the whole thing isn't just one guest per episode. At least I hope they all team up in part 5.
It's so confusing to have two characters in the franchise named Nora, and to have them both get referred to in the same overall apartment scene. First Barry and Iris talk about being visited by Bart and Nora from the future, and then a couple of minutes later they're asking Ray how he and Nora are doing, without bothering to clarify the distinction. And then there's Speed Force Nora further complicating the issue.
They did a pretty good job with Despero. I feared they'd be downplaying his alien appearance, but we got the full giant CGI alien in extended shots, and the animation was good by Arrowverse standards.
I'm worried about Joe. He was inexplicably absent, and Cecile looked upset when Chester said "dead," as if he'd touched on a recent wound. Hopefully they're just faking us out.
The Royal Flush Gang was a nice "villain of the week". And cool that they go back to the series pilot.
Actually they don't. This is a post-Crisis retcon. There were two pre-Crisis Royal Flush Gangs, one that appeared in episode 6 of
Arrow and one briefly featured in episode 11 of
The Flash, and this one seems unrelated to either of them. The
Arrow RFG were non-metas and were sympathetic villains who didn't hurt innocents, so they were the first bad guys that Oliver chose to take alive. The original
Flash RFG was just a three-man motorcycle gang that the Flash took down in the teaser of the first Pied Piper episode.
