Crazy talk. I know it's popular to bash, but if there's one thing the Fox FF got right, it was that these characters had a (developing) relationship. And their Johnny and Ben were absolutely perfect.
Johnny and Ben were the only people that cared about in those movies.
I thought Chris Evans was good as Johnny, but I thought he was even better as Captain America. It helps that CA and Avengers blew away both FF movies in terms of quality.
