Megamix is the third and final movie series in the Regular Show Cinematic Universe (RSCU), and takes place after the Theory of Everything movie series, and the Regular Show 2-part special, consisting of Inception and Challenger.
The first movie was announced at its very own dedicated Regular Show panel at San Diego Comic Con 2019, and was eventually released on June 24, 2022. The final movie, This Is It, was released on August 27, 2032.
The series has garnered high praise, similar to the Laff-A-Lympics movie series. It was addressed at the first panel that the writing, in the words of one of the writers, would "...avoid being a swear-fest with some occasional explosions". It was also said that the series would take a step back from getting to the action immediately, and take a unique approach and do something never done before in the RSCU. Critics were quick to go to skepticism on this new approach, as predictions and rumors were rampant, but when the trailer for the first movie was released, public opinion among fans and critics became much more positive. When the first movie finally released, critics were quick to say that it was the best film in the RSCU. Throughout the movie series, critics applauded the character development, emotional depth, and the fact that character death finally meant something in the universe. Reviews among the fanbase were also widely positive. Review magazines and websites like The Hollywood Reporter and The New York Times said that this was a great way to end off the Regular Show Crossover Saga.
