In some ways, Tangled is a surrender to convention--a doggedly traditional Disney fairy tale done up in high-tech 3D CGI animation. But it's hard to grouse when the results are so much fun. The animation is lovely. The story (about a proactive princess who uses a charming thief to escape from her ivory tower) is clever. And the jokes (Max, the intrepid, law-enforcing horse scores big laughs) are well-constructed. All in all, another Disney classic. 93 minutes PG.
