i honestly think everyone's freaking out a bit too much? i mean it used to be pretty common for cartoon network to do this sort of thing, no one thought the grim adventures of the KND was gonna work either, but i though it was pretty great. hell even nickelodeon did it with the jimmy timmy power hour, which i loved as a kid! it's a good way for shows to swap and share fans, and uncle grandpa isn't that bad! it's supposed to be funny and mindless, like spongebob. that's just my opinion anyways. then again, i'm pretty biased when it comes to needless crossovers.
