I'm not sure I understand your logic. Assuming you'd be the only one adding content about TV shows here (although that's not the case), you'd still be the only one adding content about TV shows there, too. The difference being you'd have to also do the hundreds of hours of work to get a new wiki off the ground.
Unless you have a solid plan for making the new wiki a success, I don't think I can support your request. I'm sorry.
