Terrible!
As an avid street fighter fan and competitive player, I can honestly say that this wasn't funny in the least. The jokes were awful, over used, and made no sense. The whole thing was just a giant mess, especially the script. I found Brawl taunts to be somewhat entertaining, but I was a mindless 15 year old who really liked smash at the time, what did I know about good humor? Now I see this. This mess of a flash with a terrible script, terrible jokes, and terrible voice acting. Spazkid was right about this flash, and made a response flash that was funnier than Rina-Chan could ever hope to be nowadays.
The cameos were just annoying as hell. The King? Sonic? The King had no purpose in the flash, and we've all heard the comparison to Guile's sonic boom and Sonic the hedgehog.
The animating was decent, but it couldn't redeem this piece of garbage.
