Rewatching this season of Flash I have to say it's better than I thought, a number of things that felt uneasy were stabilized and knowing this a rewatch has been enjoyable. HR in particular is much funnier on the second watch through once you aren't assuming he's up to no good. Which overall I find fascinating.
While there's been no evidence for it, I kinda want Savitar to be Eddie pissed off that he died for nothing.
Supergirl, Arrow, Legends, have all been better than their previous season.
