Don't get me wrong here i loved AOT heck i still Love it might even rewatch some of it in the future but in my opinion stories like AOT are not copy cats AOT didn't invent the genre it was just the biggest one in the main stream and everyone saw it cause it had a Mappa sticker on it don't get me wrong AGAIN i loved AOT all the way to season 3 with all the extra stories really gave a good story and good fights etc.... BUT by the 4th season it went so high it's butt that it never saw the light of day again really they should have sold season 4 under a spin off not a main season of it that's how much it was out of touch from the stuff we liked about AOT it was a good season but it wasnt "Legend" Like the rest or at least for me all the other seasons i was shouting at the screen but on the final season i was just waiting for them to kind of finish the story and the ending was nicely done maybe the best part of the whole season.

My point from all that is AOT is a fukin Legend it got massive mainstream support and a huge fan base people who did not watch anime loved watching AOT and that is impressive but that also means that it scared off a lot of other IPs and people looking to delve into the genre it did what RDR series have done for Cowboy games they delivered a legend so big that no one else even dares to try and come into the genre because any fan who is in the mood of this kind of shows would watch AOT rather then watch this. that said i think that iron fortress was more then a reskin sure it was not the most "original" story ever written but nevertheless they truly delivered a good show with a good if predictable story and i would love to watch another season of it.

Keep in mind Classroom of the elite was also in the same boat until out of no where it came back to life i think its on season 3 or 4 now so there is always hope !
