SPOILER-free review:
First, let me tell you the things I liked about this movie:
- cast (aesthetically, not regarding their acting)
- action scenes (not all)
- most of the movie until the part ~1:20:00
- Hana Sugisaki's acting
- Miyavi's talking voice

then the bad things I abhor:
- (sorry to his fans—he IS good looking tho) Fukushi Sota's acting
- everything after 1:20:00

Summary: Despite my low rating, THE MOVIE IS STILL WORTH WATCHING
If I were to make an alternate title it would be: SOMEBODY SAVE THE QUINCY


SPOILER-ful review (read at your own risk):

Around the middle part, I was quite impressed while watching and was already thinking of giving it a 6 or 7 or 8 and if I could end the movie already, I would end it at about 1:20:00 because that's when things went down the drain.

Everything was making sense, at least to me, until after Renji went and [SPOILER STARTS HERE] stabbed Uryuu (I WAS SHOCKED, SERIOUSLY. AND WHO THE F*** SAVED HIM) but that doesn't really bother me. I will tell you what as I go along. So after that of course they went on to fight and then since Renji couldn't slash with his sword anymore (WHY, it's not even broken Renji. so WHY), he decided to use his "Bankai" no problem with that ONLY it didn't look great at all and was like an awkward whipping slashing scene and Ichigo was dodging and all that. And. It's just awkward, for me. The more awkward part of the bankai thing happens after that (hint: Renji doesn't like slashing with his sword) but okay I'm not gonna spoil it for you, but to be real I really, really hated that part. Anyway.

After that some things happen and Byakuya enters the fight. [SPOILER-ful] For 3? times he goes and slashes Ichigo *lightning-fast* but Ichigo, being the complete idiot that he is, just goes on saying "I'll protect you" to Rukia like, are you trying to convince anyone here? Because .... Then he goes down 3? times. Miyavi does the sword-sheating thing 3x (I liked that actually because it looked pretty cool). Then Rukia (ILY Hana Sugisaki), being the sensible reaper that she is, convinces everyone to let Ichigo go in the most ... obvious (lie) way possible. But hey she succeeded because, other than Hana Sugisaki being a superb actress, somehow the movie has to end while I scratch my head, wondering. WHY—WHY—WHY does Byakuya even have to order/insist to kill Ichigo in the first place if in the end he's just gonna agree to let him go? What happened to the logic department? I know it's for the sake of the happy ending BUT for the love of what's holy why does he suddenly go backwards—I was already convinced that Miyavi is a RUTHLESS ONIISAMA but... yeah I'm really sad about this. As an audience, I really, really despise being treated like an idiot.
*end rant*

Sorry for the rant. But other than that. The movie was pretty great as I already said just before the ~1:20:00 part. And it's worth the watch. It's short, so do it. It's on Netflix. My saving graces were Hana Sugisaki's acting (I couldn't stress this point enough) and Miyavi's talking voice (mhmm).

P.S.:
WHO SAVED URYUU COULD ANYONE ENLIGHTEN ME?
