"utterly failed " yeah right. To me the IBO fights feel completely different than Seed , Wing or 00. For one Gundams in IBO are not overpowered like in those shows, making the fights longer and far more interesting and diverse, and also all the characters feel more human.
I can completely understand your perspective if you're just looking to compare
Iron Blood Orphans to those particular shows from the recent past. However, you'll note in my post that I wasn't talking about the last 10 - 15 years. I am talking about the entire
Gundam franchise and the entire mecha
genre. That's over 40 years of mecha anime - that's where I am coming from when I am chiding
IBO for it's failure to distinguish itself from the rest of the world of mecha.
Would you like to see more down-to-earth (or 'realistic') mecha combat? There's plenty of it out there.
Gundam has dabbled it in in works like
08th MS Team and
War in the Pocket. Outside of
Gundam we have lots of other contenders such as
VOTOMS,
Mellowlink,
Break Blade,
FLAG and even to a small extent
Patlabor.
You talk about characterisation? Well as crazy as Tomino even, the original
Mobile Suit Gundam (1974) certainly has more fleshed out and believable characters than something like
00. There's not much point picking out individual mecha shows that do this better or worse because, by the by, most writing in anime tends towards the exciting rather than the realistic.
IBO isn't really striking out to original territory by focusing on child soldiers because mecha as been telling those kinds of stories since the 70's.
Once you've seen enough
Gundam shows, or enough works in the
mecha (or any genre) you soon find yourself tiring of seeing the same old tropes trotted out again and again. This is why
Gundam Build Fighters was such a breath of fresh air because it decoupled the exciting action of
Gundam from the very-well worn and largely tiresome space politics which often acts as the anchor around the franchises neck. By severing this link it managed to revitalise the entire concept and bring something new to the table.
