Of course, we may never actually know if the series is a hit in the good old U.S.A., given Netflix’s secrecy regarding its viewership statistics.
As mentioned, popular British shows tend to do well in the United States, so there’s reason to suspect Bodyguard will have some success in America.
It definitely helps that the drama is led by Game of Thrones’ Richard Madden, who still has folks stateside crying over the loss of Robb Stark.
Regardless of how it performs, it appears the chances of a Season 2 happening at The BBC are high given its ratings triumph, which means Netflix would probably continue to carry the series no matter how it performs on streaming.
