Rampage (out Apr 12) stars Dwayne Johnson and is about a gorilla, wolf and alligator who come into contact with a DNA-changing gas and transform into giant, angry creatures which threaten civilisation. This had the makings of a tense action thriller but turns out to be goofy, poorly-written movie where the villains are exceedingly dumb, the heroes lack personality, and comedy is largely absent. Grade: C.
