I don't realy see the reason for the fuss about the last order being so bad to be honest...
Actually, I may be one of those few who actually prefer last order..
Aside of year of release at which it was done, gunnm barely had anything special.. Yes, it was a great read and such, but something brilliant? Not at all, maybe IF it was a shonen type manga and not seinen I would tell it's great for shonen.. but it's seinen.. and I will be honest, seinen is my favorite type of manga and it's not for the reasons of nudity/brutality, it's for the reason of mature content, which is not realy the case...
First gunnm had just quite a few flaws, starting with how purely illogical the characters were done up till the point where there wasn't anything overly brilliant(if we read it nowadays, for the time of release it surely would be amongst the top)
The only point that saves gunnm is sheer enjoyment - it's not your typical shonen, where you can already guess miles ahead that protagonist will never lose and such, it added some diversity here and there and a few twists to mix in, so it was a good work overall :)
Now why I prefer last order.. well, probably since it improved on the humor side.. a few jokes here and there sure relaxed the atmosphere(maybe even a bit too much, tho).. perv jokes are also always welcome for me, hehe :D
Also the characters became more.. logical(?), well, at least you could see the reason behind some things now without having a facepalm or two..
Out of bad sides in the order up to date for me was the DBZ effect... it just feels wrong how characters get such massive power ups pretty much out of void..
Well, now I am realy looking forward to the grand finale during the summer anyway :)
Frau x probably being alita's childhood friend, heh.. the only thing that seems wrong is that the one to encounter her will be brainchip alita and not the real brained one..
Well, maybe they will actually unite or something, we will just have to wait and see :D
Not realy expecting too much out of finale to be honest, but a simple closure will do for this series, as it's not the series I watched for some deep philosophy anyway..
