I love 90% of the game, so I'm probably not as far off from you as you might think.
I'm up to chapter 13 now, and boy does it fucking suck. A bunch of straight line hallways, the biggest enemy of this game's camera, crammed with giant flying enemies that make me even blinder. I had to put it down, it's just too stupid. Then I get to continue refighting bosses

I'll beat it tomorrow though.
3 months in the oven would fix it for sure. that laggy staircase was a total fucking embarrassment, but it really wasn't a surprise. I don't know how they went from having one of the best looking, cleanest, smooth running, perfectly balanced games of last gen and turned it into a rough package like this. I guess that's what happens when the lead designer decides he's quitting halfway through the process.
It's a shame that 10% is so strikingly awful because the 90% is fluid, perfect, everything I wanted, and maybe just enough to keep me from ever touching NG1 again. I already want to replay the game but I doubt I'll do it anytime soon (or on higher difficulty) because those little 10 minute spots of annoyance really throw a monkey wrench in the 12 hour experience.
DLC level select please, Team Ninja, if you even give a shit anymore.
edit: Oh, but I think I'd have to say that "more enemies" is more a con than a pro, especially with the camera.
