Honestly the only good part of this show in my opinion is the first half of the first season. after that the whole anime is just so dumb, if I'm not blind I'm pretty sure all the characters have some form of kiritos facial structure in alicization. other then design the story doesn't really make sense, only s3 and s4 make a little sense. mainly because half of season 1 and 2 is filler. watch if you want to be disappointed
