I loved this show and am looking forward to a season 2 if it is ordered. I have never been a big fan of origin stories because they can be slow at times and the first couple episodes felt like that to me here also. I am so happy I continued to watch.
The story, while fantasy, felt believable because of how the characters deal with the real life in the midst of all the fantasy stuff. I think there is a good balance of real life and super hero.
Last thing, if you are like me and have a bit of a hangover from all the anti and flawed heroes on TV in and theaters, this is a nice change of pace. Sometimes, I just want to root for the hero without having to weigh the good and bad. Lol
