Netflix isn't the only big player on our list of the best streaming services that plays it a little coy when it releases trailers for new series and movies. Typically it can be a little hard to judge whether a new show will be appropriate for all viewers since trailers don't open with age ratings or certificates.
Occasionally, though, it makes things more explicit – and a trailer for its imminent Western series American Primeval might just be one of its bloodiest ever. The trailer's even labelled as the "Official Mature Rated Trailer" to underline things, and it's full to the brim with scalpings, wounds and violence.
