Just finished season 2 yesterday actually. I didn't hate it like most, but there is a noticeable drop in quality for sure. Still thought it was decent though, and it did remind me a lot of GTA and Micheal Mann films.
With that I have to agree with, it's pretty weird to me to see people saying they disliked it after watching one episode. I mean, it's their right, it would be ridiculous of me to imply you have to force yourself to watch something you don't enjoy just to make sure you're not enjoying it, but when it comes to direct comparisons, then you should definitely know both products with at least more depth than one episode.
Haven't played the XB1/PS4/PC version of GTAV so I expected it to be about the song actually being in the game. Still though, very good opening put together, haven't seen S2 (Despite all the negative opinions I'll give it a go eventually) but the S1 is so good and I'm one of the few people who truly enjoyed GTAV throughout.
