It's not a show I'd let my nephew and niece watch (8 and 6). For me though, it's the best show on television. Don't forget the 10 webisodes that are being broadcast on the net every Tuesday and Thursday until the new season starts in October (8 days away).
BTW, has anyone noticed something about this? Sci-Fi usually shows their original and/or best series during the off-season from broadcast television. For instant, the Stargates have always started in the summer, gone into Hiatus during September, and then come back with new Episodes in January. Sci-fi has always stayed out of the November sweeps rat race. Now they're hitting November with a line-up of new episodes for BSG and for Dr. Who (okay, Who is new to the US, not new to the world as far as the new season goes). It's a nice change...
