Never let it be said that really bad movies don't make good TV.
Sharknado 2: The Second One, the second chapter of what looks like becoming a bona fide franchise for the SyFy channels worldwide, drew 3.9 million viewers in the US last night.
A total of 1.6 million of those were in the 18-49 demographic, which is the segment of the viewing audience most desired by American advertisers.
That's more than double the first Sharknado film, which drew 1.4 million viewers in the US on its first airing.
Last night's sequel, which picked up the story of high-flying, man-eating sharks in New York, also beat a number of network shows, including Fox's So You Think You Can Dance and the CBS science fiction drama Extant.
All told, not a bad result for a B-movie on a basic cable channel.
According to Syfy, the social media blitz made Sharknado 2 more popular than any Game of Thrones episode (including the Red Wedding) and #MileyCyrus on the day of her infamous MTV's 2013 VMAs twerking performance.
Syfy estimates that the sequel generated one billion Twitter impressions, although Nielsen's Twitter TV ratings suggest it was more like 67.2 million impressions.
At one point, it said all 10 trending topics on Twitter in the US were related to Sharknado 2, although Nielsen Twitter ratings said that figure was nine, not 10.
According to Nielsen Twitter, during its premiere on Thursday (Wednesday night US time), 581,000 tweets were made about the movie, which was 83 per cent more than the original film scored, with 318,000.
While SyFy showed the movie in 86 countries, New Zealanders didn't get the chance to watch it on TV. The first movie was shown on Prime some months after its US surprise success last year and Sky will show the second instalment at some point. It hasn't been scheduled though.
Sharknado 3 has already been confirmed and will chomp its way onto television screens next year.
