I'm very deeply concerned that we're not going to see the stalker angle with Zoom in this version. The way they're introducing him as a cop played by an older actor, it just feels like they might stray away from that, which would suck because it is basically Zoom's defining character trait. He's the Flash fanboy who took his obsession to a dark and violent place.
Honestly, I'd much rather see them ditch the time travel element than the stalker element. If there's a choice between the two, I'd make him a modern day flash fanboy who goes dark side.
