Oh man there are a couple of ads that are frequently appearing in comics these days that bother the shit out of me. I'm sure you'll all agree.
1. The Wii Ad.
This ad bothers me so much it makes me not even want to play with a Wii. The comic format for ads is annoying, but this one is especially grating because it fools me every time. I always read the first panel before I'm like ...wait a minute, I know this kid...It's that damn Wii kid! Aw man! Usually comic ads don't blend quite so well with the actual comics.
If the comic ad doesn't feature members of the Justice League or the Archies preaching the greatness of Hostess snack cakes, I don't want to see it.
2. The Family Guy video game ad.
It's big, it's loud, it's annoying. It tries too hard to be funny but fails anyway. It's...JUST LIKE THE SHOW! And it's often right on the inside front cover, serving as a jarring contrast to the often spectacular first page of a story. I think the best example is from The Authority #1:
Arrrgh!! Gross! I hate you, Family Guy! I hate you so much!
3. That HeroQuest ad, which I am not going to scan for the very same reason that makes me hate it: It's freaking gigantic. Pages and pages of boring, nerdy nonsense that tricks me into believing that the comic I am picking up is going to be extra-long and packed with awesomeness Nope. It's packed with HeroQuest.
Go to hell, ugly ads. Stop uglying up my comic books.
