The Flash writers have amnesia

Literally nothing in this show that's Kind of overpowered reappears for more than two seconds, examples include: the Flash being able to fly, the transmogrification device, him being smarter than a man with an IQ of 185, literally any speedster other than Nora when they're needed, him being able to react, run, and fight fast literally anything that doesn't make their writing easy just gets completely ignored
