I have very little recollection of the Shrek movies and don't remember the Puss in Boots character much, but yeah, this movie was pretty good. The Spider-Verse-esque style looks great and some shots really stand out. The arc of coming to terms with one's previous life is pretty decent, too, and the other characters mostly work. I do think the arcs could have been a bit deeper, but this is a 90-minute movie mostly aimed at kids.
