Movie critic Bruce Miller says “Tiger King” is exploding on Netflix. The seven-part documentary has so much jaw-dropping information to impart, it’s impossible to leave, even if the editing and storytelling leaves a little to be desired. Also this week we get “Trolls World Tour,” the animated sequel that was expected to rock theaters – if it had been able to open there. While the kids will love the film’s colorful animation, parents will like the way it gets you up off the couch and into move mode.
