Best sci-fi available ATM The first episode didn't move me much. I went into it with all sorts of expectations and preconceptions. More the fool, me.
What we have is darn good newish talents all over the world getting support from world class directors, good story tellers, plus locations to die for as an actor. All that going on and the series still delivers near seamless story telling. Heck, I'd marry the lot of them, which if you watch the series will make more sense.
The action sequences are in excellent hands, so no worries there.
If you're a bigot, or homophobic, or think the younger generations are going to the dogs... maybe you should watch the show. If you're none of the above, maybe the show will tell the story in a new way. Walk a few safe minutes in the steps of someone from a different culture. It's not a spoiler to say there is plenty of diversity and culture to walk a few steps in. A few scenes notably in Mexico could have had me fast forwarding, but it turns out I was prepped for it. Remarkable. It's also only part of the story, although the rest would involve spoilers.
Nudity is to be found in most if not all episodes. Mundane situations, sex in a relationship, the odd flash, one OMG extended moment. I'd rank it about a 9 out of 10 for netflix, but only a 6 for one of the big cable companies and a 2 against any of the "late night" series on cable. It's obvious netflix is pushing their boundaries. No complaints here, which is why this paragraph is longish.
