To be completely honest, you might as well skip it. In terms of its production quality, it looks absolutely no better than the TV show. Oh, how I miss the time when theatrical productions looked dramatically better than their TV series counterparts. Sometime in the 2010s, anime movies lowered the bar for themselves into the absolute ground. Compare the difference between the original series Naruto movies and their afferent TV show versus the Shippuuden movies and their afferent TV show. It's beyond pathetic.
Aside from looking completely boring and unappealing, the plot adds absolutely nothing meaningful to the narrative that you don’t already know from the show and merely ties up a loose end you almost certainly didn't give a shit about in the first place, so the story is boring and unappealing, as well. It's more of the same rushed, anachronistic-feeling bullshit from the last half of season 5.
As if to add insult to injury, this movie comes up with an almost entirely original OST, which, how best to describe this... just fucking sucks. It only lets you hear one of Hiroyuki-sensei's creations at the very end.
