I have watched all of them, and it gets more and more interesting. The last episode really left me wanting to see the next. I couldn't miss it now at all. Great mystery, but is falling in place now.
I also don't like shows with sex stuff, nothing but curse words (surely they learned how to speak more than just 4 letter words), violent shows like criminal minds, but love most animal and nature shows. We love good hearted shows like the little couple, and good hearted movies. I agree we know all this is out there, but I do not invite it into my home.
