The character designs are ugly af. The end.
At least effort has been put into it.
Boi don't take somebody's dislike for your favorite tv show personally. Nobody has the same opinions as you do. Anybody can like COD over Mario, or Pineapple Pizza (subhumans) over Pepperoni Pizza. Anybody can enjoy anything, or anybody can hate anything. Nobody is the same, and nobody will ever be the same. You can't force your religion onto somebody. It's a brand. That's all there is to it. You can watch Doraemon all you want, but don't expect people to spoon feed you how great your show is. This is the internet. The Wild West. You best be careful where you step, because those bandits and outlaws are lurking around every corner hunting you every second. Make one small move and they'll have you wrangled up and take everything you have. Online, there are no rules.
Your add-on looks good btw
