Think of this movie as a cross between Jaws and Sharknado, and you will know exactly what to expect going in.  Of course, the plot is improbable to say the least.  The Meg of the title is a prehistoric Megalodon, a gigantic ‘extinct’ shark that was said to grow up to 75 feet long, and could eat whales!  The science (sort of) they use to establish how it survived all those millenia and is still around today is pretty farfetched, even for these kind of movies.  Be that as it may, a group of scientists are trapped on the bottom of the ocean after The Meg trashes their submersible.  It is up Jonas Taylor, played earnestly by Jason Statham, to rescue them.   After he does, they of course have to go after it before it goes on a rampage at a beach so packed with people, it makes “Jaws”‘s Amity Island seem like a deserted beach.  And of course, they don’t catch it – right away at any rate.  Rainn Wilson is a really not that evil as the bad guy who funds all of the science.  He’s nice, until he shows his true colors. Statham is also given a pretty improbable love interest.  This movie is at its best when it shows the shark.  It is at its worst when it tries to add humor and pathos.  Nothing here gets too scary or too gorey – there were a lot of people in the audience with kids.  Because of that, the whole thing plays like a 50’s movie.  I almost expected to see giant crabs or maybe even Gargantua.  Despite giving this movie an apple core, I say go see it if you want unadulterated mindless entertainment, not to mention a cute little dog that seems to swim forever.  Sometimes, that is all we want out of a movie.
