When the trailer for this movie came out, everyone thought it was just a rip-off of the original Die Hard. In reality, its actually Die Hard with the female antagonist from John Wick 2 and the building climbing scene from Mission Impossible: Ghost Protocol. It's an attempt to modernize Die Hard for today's audience. A misguided attempt because today's Die Hard is still the original Die Hard. Pretending Skyscraper isn't an imitation, it's still not that great of a movie. It's exactly what you expect from the trailers, if not slightly better.
The first two-thirds of the movie are surprisingly moderate. A generic action movie with decent CGI, a step up from other Dwayne Johnson produced movies. There is nothing really egregious in this part of the movie which was a really big surprise for me. It suffers from problems that a lot of movies have today. Predictable plot, poorly directed action sequences, and ok acting. It is a way more solid movie than the trailers made you believe. The one main thing I can point to that was extraneous was the opening scene, it had no place in the movie.
The movie is noticeably worse in the last act. It suffers from bad story progression by having characters do things that don't make sense. It also has weird dialogue choices that make the movie cheesier than it needed to be. It tried being a family action movie but fails at both. There is little action and the bits shown aren't satisfying to watch. The over-reliance on family to push story is annoying. This is mostly due to the fact that I don't believe that Johnson's character cares for his family. You can feel the distance he has from his wife and the fake worry for his children.
You could go see this movie in a theater with the three other people that are going to be there. Or, you can rent it at home if you really want to watch it. If you don't need to see every Dwayne Johnson movie, then totally skip this one. Go back and watch the original Die Hard. I saw it recently and it instantly became one of my top three favorite movies. Skyscraper is just another mediocre action movie.
