This movie deserves a 5-star.
This movie is a masterpiece that I can't get out of my head. First I would like to point out that the soundtracks are stunning and add so much emotion and excitement to the movie.
This is one of the few movies that made me truly emotional. Because of the masterful mash-up of comedy, tragedy, and an overall plot, Wandering Earth 2 had me very emotional. Wandering Earth 1 made me cry as a child, and Wandering Earth 2 did not fail to complete that task either. The colour theme, complicated and exciting plot line and the multiple struggles they had to fight through really went to my heart.
Another amazing factor I would like to point out is that there is not one scene wasted. Every single frame is truly action-packed or meaningful. They are either explaining the background story, humorous, sad, or just a stunning image such as the shot of the floating city.
I believe that this might be one of the best movies of the decade. It is parallel and maybe even better with movies like Interstellar (though some people would disagree.) The amazing plot was written by the author of 3 body, plus the amazing CGI really made this movie a lifelong experience.
