That's kind of the same thing with me.

I don't see it as a show with a plot that includes song and dance numbers, I see it as a show about song and dance numbers that writes the plot around that. (ie, the only reason I think Jesse got the name he did was so that Finn could sing "Jesse's Girl.)

I pretty much only watch it for the choreography and song track. (I was in a fit of squee when Kurt sang Rose's Turn.)
