I gotta say this was pretty hard to watch. I'll try and critique as best I can without sounding like a royal prat :<.
First and for most write a proper story. This felt like you making it up as you were going along and it made no sense. Secondly, the images in the text boxes were ugly as sin, as were most of the sprites and the font you chose. You should never use Times New Roman font :<. The characters from animes, games etc and some fan-made characters just made this non-sensicle. It's like you're trying to add as many as possible, and the outcome is just... what is this? I couldn't even finish watching.
Interms of critique, all I can say is start smaller. WAY smaller! Learn some basics about animation, get an idea of how to write a compelling story and create characters that an audience can relate too/enjoy watching. If you are going to use sprites, keep the characters in character. Vegeta saying "I made a funny" felt awkward and out of place on so many levels, or even get someone to help you with writing. On the subject of the text boxes though, if possible you should bypass that entirely and just get voice actors. Text dialogue in Flash animations is so 2002, in this day and age good VA should be standard.
I will however give you one star because you are obviously still learning, but considering that there are so many movies like this on NG, this will just get swept up as being nothing special unfortunatly. If you want to make something that will get tons of views and a good score, you'll need to practice. Make shorter animations and try new things.
I don't mean to sound like an ass, you have potential! You just need to practice. :>
