...i don't even remember this.
it was one of the first few episodes after Wally got powers where they fought on the roof of a building or something -- and yeah it was inexorably dumb
one of the biggest flaws with the flash that i've been able to overlook until now are the inconsistencies. always been able to handwave here and there Barry slowing down to get punched in the face, not saving someone from a bullet (despite being faster than lightning), and not just taking out every standard villain by speeding up to them and removing their gun/face/whatever. they slow him down, de-power him, or stupify him to different levels every episode to suit the villain or plot of the week -- it's just an absolute inconsistent mess.
this season had all that but the main story was also just jumbled, sloppy, and made absolutely no sense despite having a workable premise (barry goes evil mode in the future, haunts his past self). i'm not even going to point out specifics because it at every turn, every where there was some dumb plot hole and stuff that just plain didn't make sense
you gotta suspend believability for these shows to begin with, but they asked way too much this time around -- have to suspend every ounce of rationality or logic to enjoy this season. and yeah a big part of that was an escalation of the tech mumbo jumbo as someone said, oMGGGG huge threat, last 5 minutes wait i came up with a super muzzler dimension fizzler ezzzz. also i get that time travel is messy to begin with, but it would have been nice if they sat down and came up with some basic principles of time travel for their universe and stuck to them rather than just making up everything on the fly, again, as it suits the episode/season. they need to maintain some consistency in these characters, in these themes, anywhere, but there is none. everything constantly changes to suit whatever they are presently writing or facing.
if i had to describe this season in 2 words it would be inconsistency and stupidity
