Very Good
I remember when I first saw blockhead on newgrounds. I was shocked to see that someone had presented that 'non sequitur' type of humour in a way that actually made me laugh. It was good back then and it has only improved with time.
I feel this is one of your best episodes. It is packed with gags and very skillfully put together. The whole thing flowed like few other movies I've seen in the portal, and the music was brilliant.
You probably would have achieved a higher score if you'd stolen a random anime theme song and placed it on repeat throughout the entire movie, though :P
