Whoever had "three" in the "How many Lego movies will it take before the brand feels stale and uninspired?" pool, step up and claim your prize! (Your prize is that you do not have to watch any more Lego movies.) The Lego Ninjago Movie, an extension of the Cartoon Network series about Power Ranger-y teens in mech-suits who protect Ninjago City from the evil Lord Garmadon, is only fitfully amusing, relying on meta-references for laughs and filling the rest of its runtime with bland action sequences. True to its roots, it feels like an overlong episode of a TV show, not a giddy big-screen event. by Eric D. Snider
