Nothing against Jeremy Renner, but I never was all that enthusiastic about him playing Hawkeye. It really only seemed like a way to capitalize on his buzz from Hurt Locker.
He bombed in Bourne Legacy too.
My problem is that Hawkeye has always been a hot dog and a rogue of the team. He has a chip on his shoulder and something to prove. Part of that is because he's a reformed criminal trying to go straight. Another part of that is because he's in the shadow of Captain America. At times, he's also a bit of a loose cannon too.
There was a time when he left the Avengers to lead the Thunderbolts because he wanted to step out of the Avengers and Cap's shadow and be a leader for his own team. That was a big turning point and moment for Hawkeye.
In the films we've lost all of that. Sometimes Renner cracks jokes, but Hawkeye has always been a bit of a Joker. He brings a lot of levity to the stories, and he has the air of a swashbuckling hero, a bit like Errol Flynn or a rogue-ish pirate.
Hawkeye has no flair anymore. He's now just a boring dad and family man. I don't want his family to get butchered. The people who want his family to go away want to see the Hawkeye they remember from the comics, who wasn't a family man and wasn't ready to settle down. They want his family to go away because they want to see Hawkeye as a single, hot dogging rogue.
In Age of Ultron, most of the jokes went to Tony Stark. Hawkeye had like one joke about shooting Quicksilver when no one was looking basically.
The problem is that killing his family won't bring back a more faithful Hawkeye either. We're just kind of stuck with this Hawkeye. And this is why we will never see a Hawkeye movie or series. Renner can't carry his own movie. It will never happen. Renner is not a draw, and he can't fill in the seats if they made a movie about Hawkeye.
