It is pretty simple and funny because of the shapes movement -u-

As good as one of these types of things can be

It's fine, considering how little effort your supposed to put into one of these animations.

Hah!

I wouldn't think a bunch of basic shapes would make a movie good enough to sit through to watch. I got more than what I expected.

If you want Johnny to look more 'heroic' especially when he's telling the big bad to go away, it's probably a good idea to either find a voice actor who has a clearer voice. Otherwise, your voice is good for when Johnny was just acting more casual in the beginning. The big bad's voice was good though, just right when you need a character who's obviously going to be bad. It was very clear the big red semicircle was a bad person. =p

So what where you thinking by having Johnny say that there's blood everywhere, and it was a gruesome scene? Generally, you would want to show, and not tell. It might be because of your minimalist approach, but if it means making it necessary for your characters to have to DESCRIBE what is normally supposed to be seen if this was not-so-minimalistic, but it's just plain silly: Johnny saying that there's blood when I don't see any. lolwat

And here's a last thing. What confused me was how you depicted bloody mary. Going by the name, I would expect to hear a much more feminine voice, and probably be given a shape that would pass on to me as more feminine.
