Hmm. I've been wanting to watch this show myself but have to many going at the time. It may be a show that takes a minute to get into, I've fell trap to many shows that I thought sucked ass, but after some reconsideration & patience, found it to be more then enjoyable. It's hard for a Showtime/HBO show to suck, because the writers are more edgy, the topics are more broad, & the overall show is more adult. It's hard to fail when your allowed almost complete freedom as to what your characters say/do.
Californication is pretty bomb, but... I don't know if that same opinion applies to peoples outside the California area. I would assume so, as many people from everywhere watch these shows other wise they'd tank, but it's hard for some to get into it because it explores a lot of the 'California' life. For me, growing up & still residing in California, it's bomb of course, I can relate to most the aspects of the show. I would give it a try, there is a lot of nudity, sex, good acting, POT USE, & even cocaine use.
