While I still enjoy the show, I kind of find myself agreeing with others that it's taken a disturbing turn toward "the dark side". I think it started with the DEA agent getting killed at the end of last season. It's an unwritten rule in comedy that you can't kill off a character unless he's a bad guy, so they re-made him, essentially, into a sleazy crooked cop to soften the blow. But there was still a question, right up to the end, of whether he was actually offed or not. Apparently so. But this stuff with U-turn - it's just not very funny, and that's the problem.
But it's still far better, and funnier, than 'Californication'. That one's been, on balance, a big disappointment for me.
