Of course it isn't. Neither is
That 80s Show a spinoff of
That 70s Show.
Fox wanted to replicate
That 70s Show, but
That 80s Show itself was a different beast, with a different style and concept from
That 70s Show. If the creators had spun off one of the
70s Show characters into their own show, or created another show about teenagers with the same basic dynamics and concepts of
That 70s Show, then it would be a cheap spinoff. But they didn't simply take a concept they'd already done and place it in a slightly different context; they created a whole new concept.
