I believe the other review mentions that this is simply a rip off of the acidwire arc, but I'd like to go ahead and point out to anyone reading both reviews that this is the original one shot that gave birth to the entire bleach series, so keep in mind that in a sense the acidwire arc was taken from this one shot. With that being said:
The bleach short story is top notch as far as one shots go. The artwork may not seem to compare to Kubo's current style, but at it's time and even on it's own it is extremely well drawn in
it's own right. The proportions are stylized but still visually appealing. The story is very well constructed and once again shouldn't be compared with other arcs in Bleach. It really does a nice job of showing the darkness even in our good intentions. And the comedy is universal and so that shows why the one shot was well received internationally. The characters are original and well built, and they backstory for the characters has enough depth to make them interesting but not so thick that you have no idea what's going on.
Overall I enjoyed it, and I think anyone who really loves Bleach would too. It's the starting point for one of the most popular manga to date, and so that in itself makes it interesting enough. Even on it's own though, it is a great read and tells a very touching and truthful story.
