MAMMA MIA! HERE WE GO AGAIN

R, 91 minutes. Through today only at Westbrook, Lisbon. Henson Alternative, an offshoot of the Jim Henson Company, creators of our beloved Muppets and Sesame Street characters, bills their content as “not intended for our youngest viewers.” These are Muppets for grown-ups. And they’ve truly swung for their fences, and a hard R-Rating, with their first feature film, “The Happytime Murders,” which is a hard-boiled detective neonoir film starring these fuzzy puppety friends alongside human actors. Unfortunately, some mildly-amusing ideas shouldn’t be full-length feature films and “The Happytime Murders” falls victim to that. — Katie Walsh, Tribune News Service

JULIET, NAKED

R, 98 minutes. Through today only at Mystic Luxury Cinemas. Still playing at Madison Art Cinemas. At a time when every other movie, even the rom-coms, seems to contain political subtext, it’s a relief to see a bagatelle come along like “Juliet, Naked.” Described as a “98-minute diversion” by producers at a recent screening, the romantic comedy is just that: a sweet-tart confection that, like lemon sorbet, cleanses a palate gone sour from too many cinematic servings of the heavy stuff. Based on Nick Hornby’s 2009 novel, “Juliet” stars Rose Byrne as Annie, the curator of a local history museum in a small English seaside town. Annie lives — neither particularly happily nor unhappily — with boyfriend Duncan (Chris O’Dowd), a film professor at the local college whose lectures make comparisons between “The Wire” and Greek tragedy. But that pretentiousness pales in comparison to the seriousness with which Duncan takes his hobby: a fan website devoted to Tucker Crowe (Ethan Hawke), an American cult musician who, after releasing his seminal 1993 album “Juliet,” seemingly disappeared off the face of the Earth. When a bootleg CD surfaces featuring unplugged demo recordings from that album, Annie, who PG-13, 102 minutes. Through today only at Lisbon. “Kin” is based on a short film by the brothers Baker called “Bag Man.” It follows a 14-year-old boy from Detroit, Eli (Myles Truitt), as he goes on the lam with his adopted ex-con brother, Jimmy (Jack Reynor). In pursuit is Taylor (James Franco), a psychopathic drug dealer out for vengeance. — Katie Walsh, Tribune News Service PG-13, 114 minutes. Through today only at Westbrook. This sequel/prequel hybrid arrives a decade after the bonkers filmed adaptation of the stage musical “Mamma Mia!” Vehicles for ABBA’s songs, the films perfectly reflect the music: guileless, emotionally raw and unabashedly cheesy, wrapped in miles and miles of colorful synthetic fabric. — Katie Walsh, Tribune News Service

THE MEG

1/2 PG-13, 113 minutes. Through today only at Westbrook. Still playing at Waterford, Stonington, Lisbon. The recently announced Oscar category for the best achievement among popular movies comes at an awkward time for “The Meg.” The movie is intended to attract a global audience of unfussy, low-demand moviegoers, so this sci-fi adventure fits the Motion Picture Academy’s new “count-themoney” grouping. But the rules also say that to qualify, the show is supposed to be good. Talk about moving the goalpost! It’s ever so loosely based on Steve Alten’s 1997 book “Meg: A Novel of Deep Terror.” Its premise is that prehistoric marine predators lurk in the ocean’s subbasement, and they are either very hungry or very angry. Call it “Jurassic Shark.” The fish in question is the Megalodon, a 70-foot behemoth with a mouth that could swallow a school bus and gigantic
