My kid is almost 8. We watch a lot of “Ninjago” in this house. So you can imagine how pumped we were (well, him specifically) about “The LEGO Ninjago Movie.” But the feature-film version of the long-running animated TV series only superficially resembles its source material, and it pales in comparison to the first two Lego movies. My disappointed review, at RogerEbert.com.
