One sign that Netflix is serious about this prestige-TV thing? Its trailers are now as artfully vague as the ones for premium-cable dramas. Bloodline stars Kyle Chandler and Linda Cardellini as members of a Florida Keys family that has done some very mysterious, very bad things. How bad? The type of bad that leads to hushed conversations in the rain and, eventually, boats getting blown up. And not in the funny way, either.
