I'm not too far in, maybe 2hrs or something, but man... it's pretty boring story wise. I'm in Act 2, just got out of the bar fight, and... boring. Hope it picks up. It feels like a poorly done modern "action/drama". The cut scenes directed by Tony Scott (RIP), and the main story done by some first time wannabe Tarantino, who's never seen a Tarantino flick. The "noir" style voice overs seem very silly at times. The gameplay itself is okay, but... eh, no hate, but it's very average to me at this point.
For a R* game, it's letting me down.
