I'm sorry to hear this! It makes me want to skip out too - but the stage show is my *favorite* musical and I've been looking forward to the movie for literal years (when they [whoever "they" is] decided to do "Cats" first, you could have heard my distressed cries in the next town), so I'll suck it up and go still (and go again if they market a sing-along version), but it'll be under protest!
It's not bad! There are pros (Cynthia Erivo, the big solos/duets, the sets and costumes) and cons (cinematography/lighting, the length, the "talk-singing" by Yeoh and Goldblum) and then there's the sticking point for me, which I suspect won't be/isn't a problem for most, namely, Ariana Grande (who turns out to be a better actress than I would have suspected but who plays Glinda as much more of a mean girl than a spoiled girl. It's a fine line to be sure but I think she falls on the wrong side here. Hard to know if that's her or the director, but, given CRA, I'm going with the director. Also, I'm reserving my judgement of Jonathan Bailey until Part 2 (I liked him, but he's not given much to do here.)
tldr: It's no Cats.
