I don't quite know what to say.
I think it was a nice effort trying to point out the flaws in Anime (especialy Yu-Gi-Oh) however i almost felt like i was actualy watching an episode there...Instead of having Mai accept the duel, she should have said something more along the lines of "No..." and walked off. But i guess it was close enough, eh?
Get some voice actors, i know you were trying to make fun of them, but at the very start of the flash i was tempted to close it due to the mic static almost completely distorting the already bad voices.
In short, don't get so emotional about a cartoon, if you don't like it...don't watch it. The best parodies are ones made by fans of the subject...
