Yeah, Zylka was fine in the role and he wasn't an outright jerk, but we didn't get enough OF him. What little was there, though, I liked. As mentioned, he did show Peter some sympathy after Ben's death. I still like that "Feels better, right?" line he says right after Peter has shoved him against a locker. Flash has been a jerk to Peter for who knows how long, and the moment Peter turns the tables, albeit in a moment of weakness due to dealing with a huge loss, rather than fight back or taunt, Flash sympathizes with Peter.
