This season was my least favorite season.
They gave us another villain that is a speedster, but thankfully they’ve confirmed a non-speedster villain for next season. Also, there was too many good speedsters: Barry, Wally and Jesse. Jesse went away, but I think Wally should too. Maybe go to a university in another city or something.
Killer Frost wasn’t what I thought she would be. Why does she change to evil just because of her meta powers? They didn’t explained that. I didn’t like her outfit either, it looked like a cosplay.
About the finale, I think HR technology was too unrealistic. It felt like Deus ex Machina. Nevertheless, it was a good finale. I loved to see Jay Garrick again and Barry being trapped in the Speed Force was unexpected. I just hope they don’t keep him away for too long, because I can’t stand Wally.
In addition to that, I think they should have used the classic Savitar, from the comics, instead of a version of Barry in a weird suit.
