Aquaman is going to be huge. The only part of the Justice League trailer I really didn't like was Aquaman because making him moody and drink a lot is stupidly cheap but people love that crap even if there's zero substance to any of it. I could be wrong, he may be great in the film but it's already a done deal as far as I'm concerned. Good news for people who want some collections though.
Partly why I'm still hoping for that long past rumoured Green Arrow prison film. (They should make him 50+ too. One and done great ageing vigilante movie similar to Grell's version.)
