I'm with everyone on the hosts based on the initial show. Chucky is the main draw and he's more than capable of carrying the show on his own (we speak as though he's real because he is). Having a framing device for the show is fine, but we're there to hear Chucky say funny things, not to hear the host hemming and hawing and being scared.
If half the show consists of the host hamming it up, that ruins the repeatability for me. Part of the draw of the street actor is the spontaneity. Sure, some of the jokes were repeated, but you felt like every time you walked by there was a chance for something out of pocket to happen, and having the show inside needs to account for that by minimizing the structure or no one will see it twice.
