For a certain class of cinephile, the news that Ben Wheatley (Ben Wheatley! “Kill List” and “Free Fire” and “A Field in England” Ben Wheatley!) was directing the sequel to Jon Turteltaub’s 2018 hit “The Meg” could only be met with joy and confusion. If nothing else, it suggested a big-budget film about Jason Statham fighting massive prehistoric sharks that would actually be fucked up, creepy and scary and weird and spine-tingling.
