Ok, this is an outdated topic, but I thought I'd hit it, since I just rented the DVD (which was released yesterday) and saw it.
It exceeded the expectations set for me by everyone I'd talked to.
Which means it was an average film
I was expecting sucky, but even Ben Affleck pulled off a decent job (again, not great, just decent). There was a plot, and the one major problem I'd heard of (how does Elektra come back) wasn't a problem (hello, highly trained SWAT team members discover her with no killer nearby seconds after her heart stops, have you ever HEARD of CPR? at least ONE of those 20 or so guys is going to be able to do that).
I liked how they interpreted Bullseye. DD and the Flash have always had the stupidest enemies, which is part of what's held them back as characters, despite being so strong. Bullseye and Fisk worked really well.
But the plot was pretty generic and they directing didn't let us linger enough on moments that could be pretty powerful. And again, the acting was undistinctive. So it could have been handled better. A sequel may be possible, but I'm not holding my breath.
Oh, and Jennifer Garner is MUCH hotter than Angelina Jolie
