I can tell you the plot now: he finds a reason to go to hell. bad guy does some stuff that is retarded and not necessary. makes other people join up and fight. lots of pointless fighting vs minor characters that never stood a chance. Semi-epic final fight, Ichigo wins, everyone acts like their lives won't forever be scarred by witnessing Hell.
I hate to admit it, but I'm actually looking forward to this movie. Mostly because of Shuren, I like him already :3 Plus it's nice to hear more Furuya Toru. I just hope this doesn't turn out to be as boring as the past Bleach movies.
