Truly great...
Very intresting piece, very unique storyline compared to the other flash movies. The battle scene in this one was nicely done. I await the next movie, I have no doubts that it will be greater then its preceeding movie.
Only critisim is that it would be nice to know if there were any Mushroom casualties in the fight, and maybe would have been a nice touch to make 1 mushroom fall or almost not make the tremendous amount of jumps in that mushroom field, because of the battle.
On a further note, are the remaining mushrooms guys that remained at their city, going to change their minds and come in as back-up later on in the next movie. Also Good Job! =P
