"Why did they miss the opportunity to name this movie "Wolf Blitzer"?". Dwayne Johnson is not just the gentle giant, he is the likeable giant who talks softly and carries a big stick AND has the brains to boot. That pleasing voice of his that is almost broadcast quality helps too. So he is all of that in this film that carries few surprises, but if you like Johnson and you are in the mood for a smash-em-up film that is pretty much paint by numbers with predictable supporting characters out of central casting, this should fit the bill.
Johnson plays a primatologist who befriends a silver backed gorilla named George, and the two communicate using sign language. But one night, from a destroyed space station, three canisters loaded with a gene mutating pathogen land on earth and in - of course - the United States. If they landed in China, Russia, and Afghanistan this would be a much different movie! One canister exposes George, another a wolf, and another a crocodile in the Everglades. Cue evil corporate baddies, the military who can be both a help and a hurt in these situations, a complete misrepresentation of CRSPR technology, and, of course, the mutated wolf flies.
Like I said, if you just want to put your brain on hold this is not a bad time passer and pretty much gives you what you expect in a routine action film.
