movies are for self satisfaction except the naruto:the last , boruto the movie is basically a spoiler for the series, and obviously series first skip all the fillers and your good to go desu~
Watch the second naruto movie. The rest are the same movie but different rasengan are the end of them. Naruto meets random person. Random person needs help with their problems. Naruto Rasengan the problems away.
Sasuke damages the enemy after giving it his all, Naruto finishes them off. There, I just spoiled the plot for all the movies. Literally, all of them. The movies are really nothing worth watching... but if you really want to watch them. The last movie is the only one that should be watched after the series, all others are filler.
