The more I see the Sad Affleck video, the more I feel bad for the guy.
He's idolized Batman since he was young and wanted to play the role since forever. The guy even built his own batcave! His kids look up to him for playing Batman, and I read that his young son thought the UPS/Fed Ex guy was the Joker because of a purple outfit he wore, and that Ben Affleck paid the guy to pretend to fight outside in the yard (Affleck dressed as Batman) making it look like Batman fighting the Joker. I don't know, things like that really warms my heart and makes me feel bad for the guy.
On the plus side, I haven't seen anyone criticize Affleck and even the haters of the film liked him. I just hope the movie doesn't tank completely. It has to make 800 million dollars to break even. Let's hope it makes at least a billion, maybe 1.3, and I think WB might still take action regarding Snyder/Justice League because of the reviews. I just hope we get a standalone Batman movie directed by Affleck.
Also, I didn't think BvS was bad. I actually liked it more than Man of Steel, but I liked it similar to how I liked Raimi's Spider-Man 3, where I have to add a "I liked it.. but.." at the end. There are problems and some of them are rather obvious and hard to look past, but there is good stuff in the movie.
