I take this to mean you like the Suicide Squad trailer? More power to you.
I hope it turns out far better than the impression I get from the trailer. Leto is the biggest wild card, and what little we see of him strikes me as a hilariously bad casting. So edgy. Will Smith has been box office poison for a few years now.
I think the real issue Warner is dealing with is that most people have no freaking clue who anyone is besides Harley, and she's far from a critically loved darling. I read a ton of comics and everyone looks pretty generic in the trailer. "Rope guy" is a thing for a reason.
Like I said, many of these same things are what I thought about the Guardians trailer, and I loved that movie. Maybe this will be DC's crown jewel to get their movie franchises rolling.
