I'm going to give this a solid 3 stars.
There's so much I didn't like about this. And yet, by the end of it, it still somewhat left me with that fuzzy feeling that the original Cats left me with.
Here are the positive aspects I will say about the movie, for one, it sticks to the lore, and almost completely follows the original play by the book which I really appreciate. Some of the songs, not all of them, and the ending sequence, brought me back to a happier time when I was younger watching the original Cats DVD, the music just moved me and made me so happy. But.. that's about all that can be said about this movie. As a die hard Cats fan, I tried to be unbiased and give this movie a fair chance, but it just made all the wrong moves.
They messed up so many dynamics about the original music that made it wonderful and memorable in the first place.
Rum Tum Tuggers part is one of the best songs in the play, and in this movie, it was one of the absolute worst parts. RTT is supposed to exude cockiness and sexuality, he's supposed to be a "pretty boy" and there was absolutely none of that coming from Jason Derulo. The major thing that sold his performance was his voice, which was really good, but his voice alone was not enough to stick to the original dynamic of the character.
Jennifer Hudson really killed the singing, she was spectacular, her voice was anyway. But she also seemed to over-act a lot of the parts unnecessary.
They completely BOTCHED the Mungojerrie and Rumpleteazer song. That too is one of the best songs in the original play, and they dulled it down, and took away everything that made the original song amazing.
They left out the Rumpus Cat song, which was one of the best segments from the original.
I'm not going to bash the movie completely. There are some good aspects to it, I still somewhat enjoyed it. And I think if you're a die hard cats fan, you'll still enjoy it too.
But there's just so much more they could have done with this movie, so much unnecessary changes they made that screw with the original dynamics. They broke that age old law of basically if it is not broken, then don't fix it.
Cats is supposed to be corny and old fashioned. You can't make it "hip and cool" for the new generation. It just won't work with something like this. Nobody ever watched Cats back then because it was the cool thing to do. They watched it because it was taboo and awkward. Nobody goes out to the bar with their friends and is like "Sup dog, yall check out that new Cats flick?" Hell no. They watch it in secrecy. Indulge like a guilty pleasure. Much like people still listen to MMMbop in their heads and yet claim its one of the worst songs ever.
Anyways, TL;DR if you're an original cats fan, it's worth a watch, but you will be disappointed with many aspects.
