average i guess
im giving it 8 because its your first submission and i think my first submission(wich dont exist)would be way worse than that...
music was ok,graphics too since its a sprite movie but i just dont see why giratina attacked mario and luigi,so,you should've putted a story behind it.also giratina's scream get annoying the 3rd time you hear it or so...and you could have made it longer instead of just saying "to be continued" and to let us wait for the sequel but im not decreasing your score for that.
