Has "Californication" jumped the shark?

I'm a big fan of the show since it started, mostly because of the writer angle. Having lived in SoCal and having been a semi-pro lothario myself (complete with self-loathing), I also enjoy the banter and challenges that Moody faces almost every episode (and there's a few Moody Moments that I can relate to from my own past -- my fav was last year when he had all three girls in the same room, at the same time, and none knew the wiser. Yes, that happens, and Yes, his reaction was spot on). I do agree that Epi 1 of Season 4 left much to be desired, but I blame it on the writing and I suspect that Showtime is going more for the sizzle and less of the steak. I was disappointed and I believe they can do better -- if they want to. It almost makes me wonder if the writers on the show can actually relate to the situation, or are they just guessing because they've never walked in those shoes? Sure seems that way to me. Viewers are subject to lots of questionable dialog that would almost never be said, in any state of inebriation or sexual excess. I do enjoy the sporadic Moody opinions about contemporary literature and what sells today (loved his take on The Twilight Saga -- and very bold of Showtime, the "exclusive" Twilight channel, to let it fly), but we don't get enough and I'd love to know Moody's take on Larsson, Patterson, et.al. Was there too much T&A last night? Yes. Did I mind it? No. Just as I did when I sifted thru the girly babble and banter within SATC to find (and savor) the gems of modern human dating behavior found beneath, I am content (for now) to accept the gratuitous T&A as the price to pay to enjoy watching (and vicariously reliving) Moody's exploits and quick wit -- I just hope the writers get the message and we will see equal amounts of steak AND sizzle as the season progresses.
