Hmmm......I think it's too early to shit on it. I mean, I'd rather be playing as the good guys but maybe Rocksteady is more comfortable doing something like this that is more similar to their Batman Arkham Games. Games that have starred DC characters that fly don't exactly have a great track record.
It also makes me wonder if Suicide Squad and the Batman game are two sides to the same story. It's a stretch, I admit but it's something to think about.
