You can't really expect BANDAI to make a full length "movie" for the website when it's intended for kids 'cause I don't think most of them would sit in front of their computers the whole time.
I didn't really understand the plot of the "movie" so I didn't find it amusing. Maybe they could have...
I'm in high school, 9th grade, 15 years young (I'm still a kid in heart) and sometimes I play with it in math class 'cause I sit at the back and my teacher never notices, or maybe teachers in high school just don't really give a *stuff* anymore.
Just make sure that all the hearts are filled in...
