Yes, “47 Meters Down” is silly in places, and I don’t think it will ever be held up as an example to students of good screenwriting.  But I can’t slam any horror-thriller that scared and entertained me.  And the sharks here (which were surprisingly well rendered by CGI) made me jump a few times.  Furthermore, there are a couple of surprises late in the story, and I thought that one of them was wonderfully well executed.

This movie actually reminds me a little of last year’s “The Shallows.”  Neither movie is 1975’s “Jaws,” but neither pretends to be.  They’re both perfectly serviceable monster movies that present horror movie fans with a great way to kick off the summer.

I’d rate this film an 8 out of 10 for being a fun, if forgettable, shark flick.
