His new movie is gloriously, hilariously crude. In the decades since, Mike Judge - the inventor and the voice of the perpetually chuckling animated duo - has gained renown as one of our sharpest social satirists, thanks to movies like “Office Space” and “Idiocracy” and the TV series “Silicon Valley.” Yet what’s so wonderful about the sequel “Beavis and Butt-Head Do the Universe” is that Judge does nothing to make his most famous creation any more sophisticated - visually or comedically. Gen-X kids, prepare to feel old: It has been more than 25 years since the movie “Beavis and Butt-Head Do America” premiered.
