Couple of things.
Firstly, the film is radically different from the stage show, and not in a good way. The stage version was/is a hipper version of The Wizard of Oz - Dorothy came from Kansas, and while there were plenty of references to contemporary black life, it was still pretty fantastical. The Film's Oz is a bizarre fun-house mirror of New York, and is to a degree obsessed with inner-city grime. It's not a good movie (though Michael Jackson and Ted Ross do phenominal work in it). They also rewrote the script significantly, which I imagine they will do again for NBC. That's fine, the script is pretty dated (funny, but dated). From where you say you stopped, you heard a grand total of TWO songs. You can't judge a score from two songs.
Which leads me to my second point. If you are going to go online and bather on about how you do not like something, actually WATCH the something you are judging in its completition. You have to actually take in a piece of art before condemning it*. The number of times I have found something to like in a piece that I thought I would find reprehensible is incalculable. If an excerpt from something, such as a film trailer, doesn't seem like it's going to grab you, that's fine. But you can't say "This is a terrible movie" unless you actually see it.
*with the obvious exception of Adam Sandler films. He's had his chance.
