I tried to find the sources on this, from what I can tell it's horseshit to drum up clickbait news. The only thing I could find is that some trolls may or may not have posted death threats on a fan page that isn't him and has since been deleted. That is not to say he hasn't or he won't. The sad part of this is that we all can sit here and go "yeah I could see that.". I blame the youth /s. There's just so many people with semi-anonymous internet access these days this kinda stuff is just common place now. People can go online and say what they want with generally zero repercussions.So apparently in an attempt to catch up to the insane Snyder fans, insane MCU fans have been sending Wyatt Russell death threats. Dude had to leave Instagram. Shame on these no life losers, Jesus Christ.
On Topic I think Wyatt is great. Whatever I don't like about the show Wyatt is just perfect. I almost believe they actually put some comic writers or editors in the casting room for this stuff and someone went "This dude is totally him. That's our US Agent." I know for a while there was a consortium where Marvel artists, writers and editors had input into casting and filming, but I don't know where that stands after the Joss wedon revolt. I also think hiring GSP as batroc the leaper was brilliant especially considering he's just there to be a C-lister.
I'm not sure how I feel yet about karli morgenthau. I thought Eryn was gonna be playing some version of Sin, Red Skulls daughter and crossbones girlfriend from the comics. I'll go with whatever works on screen, I'm not a comicbook purist, but I'll be a little giddy if she turns out to be totally dagnasty evil.
