When the gates of Hell appear in Karakura Town and strange spirits called Unforgiven (Togabito) escape, Rukia Kuchiki and Renji Abarai are sent to investigate. Ichigo Kurosaki's family is targeted by the Unforgiven, who are led by Shuren, and Ichigo's younger sister Yuzu Kurosaki is abducted.
Overall, this movie wasn't very interesting.
I'd say it was at the bottom compared to the other 3.
The lack of plot buildup was the downfall for this movie I'd say.
It also relied too heavily on the fight scenes - not that they were worth it.
The very fight scenes can be found in the episodes themselves.
In a movie based context, I would've expected something different and original.
Not fights that lasted less than 1 minute.
I'd give this movie a 6/10. 5 for the aspects of the movie and 1 for the effort in trying to dig viewers in.
