Well, as a Steph fan (shocking, I know), I actually don't hate it completely. I think Batman was a massive jerk for the way he fired Steph, and I think there's massive problems with the idea that the War Games plan could go wrong from the start, but Batman still recognizes that it's his plan, but if they'd just let Steph live and learn from the event, instead of killing her off and sending the whole Batfamily away from Gotham, I think it could have actually have been relatively decent. Instead, they went with the laziest, cheapest ending possible.
