Daredevil, the less than well received adaptation of rival Marvel's blind lawyer by day, ninja vigilante by night. I actually liked the flick in it's original and Director's Cut form but Affleck didn't embody the role in an unforgettable way like Bale did for Batman or Robert Downey Jr has for Iron Man. Well, nobody's embodied a role as well as RDJ...
I dunno, Michael Keaton was a totally unexpected choice for Batman and WB received something like 50,000 protest letters but he was great in the role; odd, dark and captivating. Val Kilmer seemed like a decent choice, handsome, a solid actor and physical. George Clooney seems like an Affleck choice; in with the studio thanks to his work on hit TV show ER and a hot name at the time. Bale was an obvious choice from an acting and physicality standpoint, he has depth, darkness and that sociopath charm but was far from a household name at the time. That foresight seems to be missing here. I went in to Man of Steel with low expectations and found it quite enjoyable. Hopefully the same thing happens for the sequel.
P.S. Affleck was the bomb in Phantoms.
Here's a great episode of Dinner For Five featuring an all Daredevil table:
