The flash doesn't suck, but this version with Ezra Miller sure does. They made him more like Kid Flash. I still haven't watched this yet (maybe next week) but Ezra is awful as Flash. So I have no desire for the upcoming Flash movie. As long as it is based on this character, there is no way I will like it or be able to enjoy it.
As for Lex...
I don't get WB at all. The last 2 versions of Lex have been so awful. Zuckerberg is one of the reasons I can't stand BvS and was never able to rewatch the UE version. The minute I see him on screen, I just think **** NO and get totally taken out of the movie. And then on CW Supergirl they cast John Cryer. I honestly don't know which is worse.
We have never seen a good, serious evil businessman Lex Luthor. I want Lex from the JL cartoon. Gene Hackman/Kevin Spacey was a petty criminal "genius" who couldn't get past real estate in 2 attempts. And awful comedy attempts. Kevin Spacey just followed the formula and tried to be a more serious Gene Hackman.
Neither ruined the movie like Zuckerberg did, but c'mon WB... Give us a serious bad *** Lex Luthor already!!!
I would love to see a Superman against Lex in some cool *** looking Power Armor.
