My proposal for a gritty Sesame Street reboot: Bertman V Super-Grover.
Damn that sounds awesome, but why Grover as Superman of all people, I image Big Bird would be better. Then again Super Big Bird doesn't roll off the tounge as well.
THERE'S STILL DAN GREEN
Unfortunately he retired after he lost his wife and is now a voice acting coach so he's not the most viable as awesome as that would be.
However according to TV Tropes Dan Green has some LA Counter Parts in Travis Willingham (K in VLR, TINY MINI SKIRTS!, etc) and Patrick Seizt (He's apparently Dio [tornado fang]ing Brando in the Jojo's Bizarre Adventure anime dub) and both do work in video games as well, the former has done stuff aforementioned VLR and various Atlus Nintendo games it seems but the latter has done things for Rune Factory 4, Magnus in the latest Smash Bros and Fire Emblem Awakening.
Speaking of Atlus apparently the USA branch merged with Sega of America, with Sega being able to publish things for them. This won't affect creative works and the companies will still have their identities, it's just strictly business.
