I'm disappointed in most of you for complaining about the cliches; everyone should know by now that anything remotely "post apocalyptic" is automatically one big cliche. And, something that may come as a shock to a lot of you: The Fallout series wasn't the first thing to bring in the idea of a post-apocalyptic world.
I agree with Diablus on the point that everyone seems to be a pessimist about movies or animations. When I watch something like a movie or a flash animation like this, I watch it to be entertained, I watch it as a deviation from normal everyday life; I don't get nit-picky about why someone's clothes are spiffy-clean or where I've seen such-and-such scene before. I still know the difference between a good movie and a bad movie, but that doesn't mean a bad movie like Super Mario Brothers or Matrix: Revolutions can't be entertaining.
Most of all, I'm surprised at the general lack of respect for someone who's putting time and effort into a project they're working on, merely to have it sh*t on by a bunch of naysayers and pessimists. Something that looks as nice as this can't be easy to create, and it's discouraing to know how many people are out there to put someone down for their work.
As for the flash itself; Overall, I like it. The model of the female is a little too close to a character from Dragonball Z, whom I can't remember her name (one of the andriods), just seems out of place, and the "End of Teaser" is a little odd, but overall it's a very solid animation.
