This movie was a very engaging spin on the classic time travel caper. The tone is more "Law & Order" and not Disney or "Spy Kids" at all. If you are expecting a G-rated "everything is awesome" type film, leaves those expectations at the door.
The director tells the story from the perspective of two young New York City teens. He asks the question how would the real lives of these teens change if they just happen to be able to travel back in time. The political upheaval, crime, and police violence in NYC are a backdrop to this story.
I thought the director did a very good job of spinning a new take on the classic time travel tale aka "Back to the Future." In the beginning there is a lot of time spent showing you who the teens are and their living environment and educational experiences. This characterization other reviewers have called "slow" but I appreciated the peak into the world of the two teenagers, it let me appreciate who they are and the motivation they had to achieve time travel.
I disagree with most of the negative reviews on this film. After reading them, those reviews seem more politically motivated than an actual criticism of the movie. This is a Spike Lee produced film, so some social commentary is to be expected. The film does discuss police violence in communities of color. The negative comments and low film ratings appear to be just push back against a film presenting a different opinion on the perspective of police gun violence. Despite having a different political viewpoint, I did not find the movie to be preachy or self-righteous, but just presented the situation in a matter of fact manner. Politics aside, this was a good movie.
