I'm on Chapter 20 or so now and the game is pretty good though I'm not a big fan of the last plot twist. The controls are a little buggered compared to Gears (which I just played a bunch again last week) and I'm not a big fan of the "leap of faith" gameplay Naughty Dog seems to have ripped from Tomb Raider.
Other than that, the story is a lot of fun and I wish there were a few more puzzles and less "send the baddies at me in waves" style of game.
PS. Naughty Dog should be ashamed of themselves for creating an AK-47 where throwing your clip is more effective than firing the rifle, a Colt M4 that actually performs decently, and an early 40s German assault rifle that absolutely annihilates the enemy. Ugh. Something doesn't make sense there. If I ever meet someone who took 9 rounds from an AK at close range, I'd like to shake their hand (if it hadn't been blown off already).
