The show was popcorn meaningless fun that never aspired to be any more.
If the movie can do that, it will be fun.
If it can do that and not feel like a parody, it will be really good.
If it can do that and also manage to be even a bit more compelling plot/character wise, it might be great.
BUT...
If it tries to be really compelling plot/character wise, it will totally miss the point.
