It was nice to see the Flash appear on Supergirl. It was a fun cross-over. Maybe Supergirl will guest star on the Flash next season. I don’t think she should appear on Arrow without the Flash.
Arrow was good this week. It was interesting seeing Damian Darkh in prison. Also it was nice to see Curtis again. The flashbacks aren’t working this season. That might the worst thing about the season so far.
I am not sure about the Flash. While the season remains fun, the villain plot is a bit confusing. Maybe it be cleared up in the next few episodes. Wally West has had a smaller role than I expected so far.
