The purpose of the movie I guess was basically to tie up plot points and what not, to wrap up the franchise, but honestly it really didn't. Just opened up a bunch more questions and confusion with too many technical term and explanations going on.
But the betrayals were done well. Some character portrayals were good but most of the supporting characters were really just a tree in the background; not much about them, they were just there to get the plot moving, and annoying at times.
Saya's character development in this is fairly minimal; she's regained control of her true self, the wish she made to Watanuki, but her true moment doesn't really shine until the near-ending of the series which was, truly sent me down into a spiral of emotions. Unfortunate, but the series wrapped up too well.
Fumito, our villain, also has a 180 degree personality change in this; it just seems like whatever he did to Saya in the anime just went to waste and that's just not significant anymore; his true goal was something completely different that really questions the purpose of the anime; nonetheless, this villain wrapped up his ending way too well and I honestly could've cried.
Characters aside, this opens up a whole plot hole as to whether xxxHoLiC exists on the same dimension as Blood-C because Saya is able to visit Watanuki's shop. Or perhaps Saya visits the shop through an inter-dimensional portal that is made only for Saya when she walks past the shop's gates... le sigh we will never know. Saya's wish and prices are never revealed even though this is what could've driven a huge part of her personal character development arc, but oh well. I'll just sigh and look past this.
