I agree that season 1 was much better than season 2; however, it does get better. Kind of ironic you quit after three episodes (not that I blame you) because the fourth was the best of the season, and things turned around from there.
I'm still rooting for it to be renewed for another season. There is still plenty they can do with Colin Farrell's character and backstory. They just need a better detective case then the one they gave us this season.
