I jumped off the show LONG ago. Don't know which season, but the one with The Thinker. I think I made it to the mid-season break and never looked back. The show's writing is often atrocious and their overreliance on evil speedsters killed it for me.The Flash season 8
I haven't finished yet, and I'm going to, but if season 9 features either time travel or the Reverse Flash, I'm done with this show. I'm so sick of both of those, and this show just cannot get over them. Like, holy fucking shit, there is so much more to The Flash than time travel and Eobard Thawne.
Aa a big Flash fan, what disappointed me the most is they barely touched his great gallery of villains. The Rogues don't exist as a group in this and that's a huge missed opportunity. Captain Cold waa quickly forgotten. Heatwave joined the Legends. Trickster appeared early in and then forgotten. Apparently Mirror Master appeared somehow but it was all about evil mirror doubles or something? Blech.
I've seen some clips here and there and now there's some kind of different elements they draw their powers from? The crap with Reverse Flash at the end looked awful, like a bad version of Power Rangers.
To me, it's just a show of constant squandered opportunities and bad writing.
