I probably have the lowest view on Paul Rudd. He's been in some of the most cringe inducing roles being outclassed rightfully by more talented people like Carell and Ferrell and I've rolled my eyes when I realized it was his scene up next. I don't like Seth Rogen and Jason Segel (outside of HIMYM) and he makes those two tolerable in their movies.
MCU has done a really good job hiring the right people for the right roles and working around decencies for certain things... and hopefully that's something they've done in this case because I want to watch Ant Man, but I definitely don't want to go see Rudd in a lead role again.
