I never saw much of the original show, so I can't really compare it to this one much. From what I saw, I thought it was good and had a pretty decent balance to it.
As for TTG, I don't like it as a stand alone show, never mind being a parody or whatever. I don't personally like any of the humour, I think it's really bad. But, I guess it must be doing something right if it's gotten such an audience, so I guess it just wasn't for me
