My first (and probably loudest) gripe about the list is the fact I see a character like Mickey Mouse who has been in existence for over 80 years, has had multiple shows on TV, has his own theme park practically, and is well known cross generations in the 19th spot on the list and some character like Angelica Pickles being in the 7th spot. What does Angelica got that Mickey doesn't have? Honestly!!! Mickey Mouse and Donald Duck both deserved top-10 spots based on longevity alone! People still enjoy these two after many many years and are globally known.
Bugs Bunny is #1....that is without a doubt. I'm not arguing that. He has a zany personality, longevity, and a global fanbase. He would always beat Mickey Mouse just because Mickey is the conservative, mature version of Bugs. Mickey is an image of a company, but Bugs is first and foremost the image of a cartoon...and that's what we're listing here.
Another thing that is odd about the list is character pairings (e.g. Homer Simpson stands alone, yet Bart and Lisa are paired together). Why not just base it on the fact that the Simpsons were a show and they should all be lumped together? Who's to say Bart and Lisa even work together as a team? I can understand a pairing like Rocky and Bullwinkle or Yogi and Boo Boo as you never see or consider one without the other, but Bart and Lisa together??? Really??? Even Fred and Barney (Flinstones I assume) are an odd pairing as they aren't always hand and hand together. Why not Fred and Wilma if you're going to pair like that?
I also think they missed out on some characters...Garfield the cat being one of them. He's been in comics for over thirty years, and had a tv show that lasted eight seasons before this was published. I guess whoever was polled forgot about him.

Apparently, the Powerpuff Girls were more important.
Too many holes in my opinion to be a good list. Maybe we'll have to make our own or something.
