Finished it, good in places, some fillers.
Also, i find the idea that this guy, who spent a year living like a hobo with all that money all of the sudden have the willpower to go back to do another game is a bit ridiculous for season 2. Unless he is trying to use his money? And saw the twist at the end coming regarding the old man.
I didn't read that he's going back, more that he'll try to bring it down. I really enjoyed it, but I don't think it needs a second season. A better ending would've seen him dead, and then ended as a one season thing.
