Last Order started out on an off key for many people, but the first four volumes continued to display Kishiro's electric artwork and the hope of more depth to Alita. However, even here many noted the shallow handling of the characters and the continual resorting to extended ultra violence. With volume five, Alita entered the ZOTT fighting tournament and the series has pretty much gone downhill from there. The art remained great, but the story and characterization were replaced by volume after volume of both endless pointless battles and over-extended back story focusing on secondary and tertiary characters, the vast majority of which had little to nothing to do with the main story or Alita's development. The title character of this series is literally not even in over a third of it.
The original Alita was a great story focusing on the character development of Alita and those close to her, whether she wanted them to be or not. It came to an abrupt, but reasonable, conclusion, due to Kishiro's experiencing an extended illness and needing to terminate the story. In Last Order, we are asked to pretend that the final volume of the first series did not occur and that this new story line is what the author intended to do. As of chapter 100 in Japan, Kishiro has become involved in a dispute with his publisher and he has stated that he cannot guarantee that he will publish one more chapter, leaving the whole thing hanging incomplete. This leaves two or three volumes to go in English before we catch up, but you should consider all of this before either starting to invest in this series or continuing to do so.
I have a number of series which are either dormant or in limbo that I do not regret investing in. The story, as far as it went, was worthwhile even without the conclusion. I cannot say that for Last Order. I continued giving Kishiro the benefit of the doubt and kept on buying the next volume hoping that he would straighten out this ever growing catastrophic mess, because I had seen what he had done in the past and the art was so good. However, nine volumes into this ridiculous, time wasting, never ending ZOTT fight has worn out my patience. Add to this the fact that Alita is barely or not in volumes 8, 9, 11, and 13 at all, which is about 30% of the whole series, and that's pretty much a show stopper for me. It is obvious that all of this other stuff is basically an excuse to extend the length of a series that should have already come to an end. The story has completely lost its focus, both on its main character and plot. I wonder if this dispute with his publisher, which is essentially over changing three occurrences of a word that means "crazy," has not been the excuse Kishiro needed to either buy time to figure out what he is doing and how to rescue his golden goose or is it to just ditch it while he can and move on to a new property that isn't so lost and caving in on itself.
Look at how glad people were with volume ten: five stars across the board. Why? Because they were so sick of the filler and were so happy that Alita was back. They thought this might actually start going somewhere. Too bad it doesn't. I should have given up on this four volumes ago, but kept on under false hope. Add all of the above together and I think that you can safely conclude that unless you are absolutely crazy about Kishiro's art, there is little reason to buy into or continue this series. If you do, the best way to approach it is as a series called "Kishiro's Eternal Cyborg Battle" in which a character from one of his previous manga makes an occasional appearance. What a shame; Alita was such a great character and deserved far more than this. When I want more Alita, I will go back to the original, which I collected in comic book form in the Eighties. As far as I'm concerned, Part 8 Number 9 is the real conclusion of this story, and Last Order is nothing but some nightmare Alita had while in the regeneration bulb before Figure released her. That is about the most charitable thing that can be said for this directionless, continuing to stall, pothole that Last Order has become.
