Huargh.
I was a little disappointed by the lack of... knowledge of Mega Man in a movie that was made by someone who supposedly loves Mega Man so much. Mega Man looked like a cross between X and the regular Mega Man and it came out looking like one of those Hong Kong dollar store toy designs or something that oldskateboard company.... Hook Ups or something... made in order to market off of Mega Man's success. If that was intended, then... awesome I guess. But if the aim was to appeal to the Mega Man fanbase then I don't think you did a good job by making Mega Man... not look like Mega Man.
I suppose by the constant references to people who helped make the movie that this was done for shits and giggles, but I didn't giggle once through the movie. The jokes were a little stale and cliché and didn't have anything to do with Mega Man whatsoever, so I don't know why you opted to use them as characters since situationally these characters can't even do half the stuff you made them do. And it wasn't in a "oh that's ironically hilarious" way, it was just in a "oh, fart jokes" way. It wasn't like, say, Spark Man trying to open a door; he doesn't really open doors in the game, it's just funny because it RELATES to his character. Mega Man doesn't eat tacos or shit or anything close to that, so it didn't do anything for me really since it didn't apply to the characters at all.
The farting went on way too long especially since they were the same three fart clips over and over. Maybe if they were varied, kind of building up to a hilarious sounding fart, it would've been worth sitting through all of it, but essentially the novelty that he was farting the Nutcracker wore off really quickly, sorta like how that same joke wore off quickly in Family Guy.
Again, I don't see why you didn't just create your own world and your own characters because it probably would've been funnier and you probably would've felt less limited in the writing because you're developing the characters on your own. But to each his own, I guess?
