Just finished season 1 - as dragon said, it's far more palatable if you watch it in a row instead of weekly.
Felt season 1 should of been entirely GCPD vs the Mob with the Wayne murders happening at the season finale. Throughout get more of a glimpse of how papa Wayne was as a person and more of his back story. Maybe, maybe a few young super villains being shown but no real storylines for them; just almost easter egg like appearances.
Too many villains being introduced kind of ruined the show for and it looks like season 2 will follow that formula even though actors and producers acknowledged that was / is the biggest flaw of the series.
I will say, it's very dark - a lot of kills and some pretty gruesome scenes. No one gouged out en eye or dismembered body parts in the Nolan films lol.
