The voices are kind of the same deal: more exaggerated and cartoony than I would like, but in keeping with the different mood that the show has from the movie and the comics. Everything else is splashy and vibrant and satisfying for its own sake, though not altogether exciting.
But none of that matters, because - okay, this is really the one thing I had to tell you - COSMO IS IN IT. Cosmo! The Soviet Space Dog! And he talks! Psionically! With his Russian accent! This show could be a pile of steaming garbage in every other facet and it would still be worth watching because it has Cosmo the Soviet Space Dog and his psionic Russian accent.
