Regardless of the backlash from fans, MAPPA is worthy of every praise for producing a top-notch finale for the AOT fans.
Ever since MAPPA took over the Attack on Titan finale from studio Wit, fans are worried about how MAPPA will pull off the series in such a short amount of time. Though the animation speaks for itself, MAPPA did a remarkable job creating believable characters, immersive backgrounds, CGI, and animations. Still, several differences are too visible, and even non-anime fans can point out the dissimilitude between Studio Wit's final products in seasons 1-3 and MAPPA in season 4.
