The Muppets themselves have always been old school; even in the 70’s, their routines recalled music hall or vaudeville theatre. So it’s appropriate that the 2014 version still harks back to ancient routines; Kermit the frog and his Russian lookalike Constantine have a routine involving a mirror that was popular before cinema was invented. The original; Muppet reboot focused not on the Muppets themselves, but on Amy Adams and Jason Segal; that’s corrected in this 2014 sequel, which opens with a cheerful song about how sequels are never as good as the original film. Instead, the focus is Kermit, who is seduced by Dominic Badguy (an ill-at-ease Ricky Gervais) into a European tour which is merely the cover for an series of robberies, leading to a hidden treasure. Kermit is mistaken for Russian crime-boss Constantine (also Kermit), who takes over at the helm while Kermit languishes in a Gulag run by Tina Fey. Appearing in a Muppet Movie has considerable cultural cache, and Lady Gaga and Tony Bennett attest, and cameos from Ray Liotta, Danny Trejo, Tom Hiddlestone, James McAvoy and many more add to the jokey feel. While not the best Muppet movie, Muppets Most Wanted is amiable enough to be going on with, with another excellent set of songs to keep things on rails.
