Doesn't deserve the score it currently holds.
On top of the graphics merely being sprites from a video game, the sound bits are also taken from other sources. Nothing aside from the vectors of the characters in a few of the scenes were created by yourselves. And while all the humor is borrowed, none of it causes me to laugh, smile, or become entertained.
Many flashes prior to this one have done the same sort of thing. However, those at least either made their own graphics or added their own humor and sound to it, and I suggest that you do the same in your future flash animations. As a whole, the flash seems like it must have had a maximum of 10 minutes of actual work, and a flash of such little effort doesn't deserve above a 3, let alone a 4.
