Well...
It was amazingly short.
The 'graphics' weren't anything special considering you used a 3d program to make them. The 3d program does everything for you, you just tell it what to do, right? The humor was stale. No seriously, I didn't even chuckle. If I were 8 years old I would probably find something funny in this...
Yes netscape sucks, but there were so many better things that could've been done to make fun of it. Firefox, was a fox running with it's tail on fire? Yes that's the logo, but doesn't tell me anything at all about the browser. Hell, none of this said anything about the browsers other than they are all dumb, crappy and have their tails on fire.
How is the flash supposed to help us out when choosing a browser? You didn't recommend any browsers that are better than the ones shown.
This could've been a great flash, but failed.
As of now, this is extremely overrated in my books. It just didn't appeal to me. Waaay to short too.
