This show is causing Dr. Seuss to roll in his grave over what Portfolio has done to his creation. This show has nothing to do with the original books! The animation looks terrible, almost as bad as Johnny Test. The voice-acting is unbearable. And the plots are very boring. Nick and Sally are essentially the same character but with a different coat of paint. Thing 1 and Thing 2 are incredibly annoying. The Cat seems like a pedophile, since he's always taking Nick and Sally on trips to weird places. The only good character is Fish. Also, why do Nick and Sally's parents let them go to God-knows-where with some pedophile? Are they drunk? I don't even know why this show is still on the air, after like 8 years. Not even a preschooler could get enjoyment out of it.
Anyways, you need to watch Ready Jet Go!, Wild Kratts, Odd Squad, Nature Cat, Arthur, Sesame Street, Pinkalicious & Peterrific, and the old episodes of Cyberchase instead.
