To be honest, I didn't like it at all.
Only one or two of them were funny.
But MGS is a great series by itself, and whether you think seeing dicks and breasts displayed numerous times and scat jokes is the funniest thing in the world and isn't at all immature, they really just abused a bunch of obscure points and nooks towards it that really mellowed as they pushed for something random and unexpected.
Sure, it was awesome because Tom said so and the animation was cool, but by the end, I think they should have just made the whole thing revolving around Snake shitting himself and Riden performing homosexual acts so I could have just voted 0 instead of having to watch all the way through and decide whether the animation was good enough to make the flash great, or if the poor lackluster jokes just made it a black hole of comedy.
Regardless if I make flash animations or not, that doesn't say whether or not I'm blind to hard work gone to waste or a true masterpiece packed to the teeth with spine-severing humor.
