I thought it was a huge bullshit and instead the film is passable for an evening of relaxation (without too much effort).
Lieutenant Mitch (Dwayne "The rock" Johnson) is a lifeguard (but do not call him that alone) that with the help of CJ (the wonderful Kelly Rohrbach) and Stephanie (Ilfenesh Hadera) has to choose the new recruits for three places in the team .
Among the candidates there are the swaggering champion of swimming Matt Brody (Zac Efron), the beautiful Summer (Alexandra Daddario) and the shy and a little clumsy Ronnie (Jon Bass). But the team is not only responsible for rescues but also for the protection of the beach and when a new drug comes out of the sand, Mitch and associates will try to find out where they came from.
The initial dislike of Matt Brody and the incidents of the dick (excuse vulgarity but it is a double meaning wanted) of Ronnie are the lowest points of the film but has a good rhythm and smiles often especially for the bickering between Matt and Summer that manages to keep it enough to brake responding to tone. Even during the investigation there is some low point (the scene in the morgue, for example) but all in all I thought worse.
Also some quotes from the original series, with some teasing as for example the protagonists who always seemed to run in slow motion (especially the girls for reasons quite obvious).
In the rest of the cast to quote Priyanka Chopra (Indian actress seen in the series "Quantico) in the role of the rich Victoria Leeds and the cameos of David Hasselhof (nice final bicker with Mitch) and Pamela Anderson (practically useless instead his cameo).
