Firstly, this film is not for kids. The Muppets have always walked that cheeky line between kid-friendly and not, with winks and nods to the grown-ups who have been dragged along. But we are about to learn what Muppets get up to when the kids go to bed. Fair warning: it is filthy and only interested in entertaining the adult side of the (Sesame) street.

In the seedy underbelly of Los Angeles, the cast of a beloved classic puppet television show are being brutally murdered one by one. Two detectives – one human (McCarthy) and one puppet (Barretta) – are forced to put aside their differences to work together and solve the case.

Director Brian Henson (son of Muppets creator, Jim) is obviously no stranger to the puppet world, having grown up learning from the master, and having directed the Muppet adaptations of A Christmas Carol and Treasure Island himself. But after spending two generations building the family-friendly Muppets/Sesame Street brands it seems that Henson now wants to blow it all up. The results are glorious – rude, crude and very naughty – making for one Muppet adventure that’s definitely not for the easily offended.

Carcharodon megalodon – The Meg – is the most fearsome predator of the deep that has ever lived. It is a 75-foot-long great white shark, with hundreds of 7-inch serrated teeth filling a jaw that can swallow an elephant whole. But this prehistoric creature became extinct over 2.6 million years ago... or did it?

Man’s presence in the unexplored Mariana Trench has disturbed the massive creature, and left the crew of an international undersea observation program stranded at the bottom of the ocean. With time running out, Jonas (Statham), an experienced Navy deep-sea submersible pilot, must save the crew and the rest of the world from this unimaginable threat.

The Meg is exactly what you think it is: straddling several genres including sci-fi, horror, action and, yes, cheesy comedy with snappy one-liners, designed to be entertaining and not to be taken too seriously. Having said that, it has been over 40 years since Jaws graced the big screen and I decided to never go swimming in the ocean again. This film does nothing to change my mind.
