With all the rumours and speculation out there, beyond the casting announcements there's hardly anything concrete. I'm taking everything with a grain of salt at this point. While Affleck does bring baggage (remember Gigli?), it is more than 10 years since he was part of Bennifer 1.0. He's a more seasoned actor and may yet surprise us.
Don't get me started on Eisen-Lex though. I will likely need convincing -- probably when I am in the theatre watching the flick.
