The boss fight has the strength of the 7 earlier enemies from the first. ep. (red, blue, orange, blue, yellow, purple, green, such creative names eh?). There are some funny moments against the purple and the light blue ones.
The next and hopefully last episode will be the fight of the good guy against the black. Then the black shows his true identity. I'm not spoiling it >:)
P.S.:The "Q" sign is to toggle the quality in case the movie slows down.
