The Flash's series finale is precisely what you'd expect from a story that has consistently underdelivered for years on end. It presents a hackneyed conclusion that display "fun" fight scenes that are resolved quickly and treats the villains from the older(better) seasons with short encounters with side characters, while Barry takes on a new villain that is at least slightly compelling if not also rushed and two dimensional. What follows is a half hour of kisses and goodbye, and some questionable decisions.
This story was once good. It had emotion, mystery, and a sort of cheesy charisma that was its own. The acting and the characters were almost always subpar, but within the context of the CW network, they were better than good enough. The second half of the show becomes this robotic and irrelevant sequence of poorly rendered external obstacles for the flat characters to move up against. This finale, as I've stated, falls within the second half. What's curious though about the shows decay, is that the problems spread not just through the artificial writing, but has infected the performances, making them bland, and then somehow the CGI too. I'm sure there are other factors involved, creative and budgetary, but this story has found itself in a position where it is no longer a functional narrative, and is in error on every level, and this finale has this all on full display. Damn you, Eric Wallace, not even The Flash could catch you.
