Despite being a Syfy film -- not the best pedigree -- the first film, "Sharknado," was so successful, especially on social media, that a second film was quickly green-lit. The original starred Ian Ziering ("Beverly Hills 90210") and Tara Reid; the sequel does, too.
The original film was "based" in Los Angeles. On IMDB, it is described as follows:
When a freak hurricane swamps Los Angeles, nature's deadliest killer rules sea, land, and air as thousands of sharks terrorize the waterlogged populace.
This time, the feeding frenzy takes place in New York City. The full title is "Sharknado 2: The Second One." It's described as follows:
The gang gets back together again to fight the skarknado.. - again.
We expect the description to be fleshed out later (no pun intended).
"Sharknado" has a 3.4 rating at IMDB and a 36 percent rating at Rotten Tomatoes, though critics rated it at 82 percent. It was so bad, it was good.
It was so bad, it became viral, too, with even Mia Farrow tweeting:
Omg omg OMG #sharknado
