I think like all long running shows they kinda end up going in a really corky direction at times. I often wonder if the writers get bored or if they burn out.
I just finished Californication Kat and I love love loved it. There are a lot of references to the 70's Boho era of which I grew up in that I can relate too. A ton and I mean a ton of music references. Lenny Kravitz daughter does a small bit in season 5 or 6, can't really remember now. And I am a huge Duchovny fan even from the X-files. He's really quite intelligent. Double degreed from two different Ivy schools. Princeton, Yale, Columbia. And I think his delivery is impeccable. If you can get over the language and raunch you might find it quite entertaining. You just need to remember that it's a show about men. How men relate to each other, how they relate to their spouses, how they interpret and navigate their world. But what I found most compelling is how deeply and differently they love. I cherish that.
