The Law of Diminishing Returns is a near impossible thing to overcome. Any efforts to match the innovative and infectious energy of The Lego Movie from 2014 were doomed from the get-go. The original film was packed to the brim with clever ideas and clever jokes. The sequel is less fresh and the joke density is smaller but the film is still a fun time.
There is no reason that things couldn't remain awesome. Phil Lord and Christopher Miller, the brains behind the first film, are back as screenwriters. Their signature pop-culture referencing sense of humor comes through. However, director Mike Mitchell doesn't quite have the same knack for visual humor and comedic timing. No one would place his previous film Trolls on the same plain as The Lego Movie.
The Lego Movie 2 functions more as a musical than the first one. There are several songs throughout and a few that are bigger earworms than "Everything is Awesome." The entire cast has returned including Christ Pratt, Elizabeth Banks, and Will Arnett as the ever-dependable comedic version of Batman. The big new addition is Tiffany Haddish as a Queen with a potentially sinister plot. The film picks up after the first one and this time the world of the Lego characters feels closer to Mad Max Fury Road than any as bright as the first film. The reason for this change is revealed in a hilarious flashback.
As fun as the film is at times, there is a piece missing. I think it is due to the fact this sequel doesn't have the emotional revelation at the end of it as the first film did. If you remember, The Lego Movie revealed that everything we had been watching was in a young boy's imagination who was in conflict with his father. Here the conflict is a less satisfying sibling rivalry.
The Lego Movie 2 is worth your time, especially if you are a fan of the previous Lego films. There is plenty to laugh about and enjoy here, including a great running gag with Bruce Willis.
