One of the least funny running jokes in the new Baywatch movie — which is really saying something because there are a lot of unfunny running jokes in the new Baywatch movie — involves these lifeguards constantly inserting themselves into all sorts of situations that fall well beyond their jurisdiction. They refer to laughable old cases that have nothing to do with rescuing drowners, a nod to the old Baywatch TV show that serves as the film’s source material and chief target. But the case the takes up most of the film’s inexplicably expansive runtime (116 minutes! For a Baywatch movie!) is just as absurd, with the lifeguards trying to bring down a drug ring and real-estate swindle centered around their Southern California beach. Ha ... ha?

It has become increasingly apparent that the best thing a revival of a tired ‘80s pop-culture artifact can be is the neo-21 Jump Street, judging by the new trailer for the Dwayne Johnson-fronted Baywatch. The parallels are striking: we’ve got the central odd couple in the Rock’s bombastic beach hero and Zac Efron’s hard-partying young gun, light meta touches about “reviving the brand,” some playful winks to the core goofiness of the source material (the “why does she always look like she’s running in slow motion?” line may be the best of the clip), even a scene where our heroes are dressed down by a furious black cop. You may call it derivative, but I call it a good start.
