I mostly liked this premiere. I liked the Flash effects, I liked that they aren't afraid to have people die. I think the pacing is great. It pretty much has everything going for it that took Agents of Shield an entire year, almost, to get going. I loved the ending where we see something from the distant future, that's out of left field and very intriguing.
The only real downers were A) the lead actor is just too bland and spineless and B) another superhero origin story yay! And the death of a parent too yay! And the old "you can't let her know about your powers" thing too yay! MY GOD, it feels like I've seen this done a million times now!
