I thought the first episode was really strong. Deals with much heavier topics than the other network superhero shows, I think it's more in the league of the Netflix marvel series. My one complaint (keeping in mind this is only the pilot) was that the main villain seemed weak. Soundtrack was at a whole other level.
I don't remember Freeland being one of the DC cities in the comics, but I was surprised to see San Francisco and Oakland mentioned in the news report at the beginning of the episode since usually DC doesn't mention actual cities.
