    Critic’s corner: What’s on TV Thursday


    Sharknado 7 p.m., Syfy

    It’s a bunch of sharks! It’s a tornado! It’s the made-for-TV movie everyone has been tweeting about! “Sharknado” rocked Twitter last week during its first airing, inspiring jokey comments from all corners of the Twitterverse, not just the pop culture people. My favorite: a photo of Mia Farrow with her friend Philip Roth tweeted by Farrow with the words “We’re watching #sharknado.” About halfway through the movie, mentions on Twitter peaked at more than 5,000 per minute. It was a full-fledged Twitvalanche. What helped start the “Sharknado” feeding frenzy? A Damon Lindelof tweet at 7:30 p.m. that read, “You folks who insult ‘Sharknado’ have clearly never lived through one. Respect, People.” However, the Twitter sensation didn’t kill in the ratings. So Syfy is wisely reairing it on Thursday night, to benefit more from all that free buzz. Don’t miss the scene in which Ian Ziering (center) chainsaws his way out of a dead shark.

    Blast Vegas 9 p.m., Syfy


    This Syfy novelty won’t be an instant legend like “Sharknado,” but it will answer the question, “What ever happened to Frankie Muniz?” The “Malcolm in the Middle” star is a frat bro in Las Vegas when an Egyptian relic unleashes an ancient curse. Pictured: Muniz with Maggie Castle.
