After listening to The Flop House episode #302 I thought it was going to be a wonderful mess filled with WTF moments every few seconds. Podcast link: https://www.flophousepodcast.com/2020/01/episode-302-cats/

Sadly, the film was fine. And the musical is not plot driven so what they added for a plot was also fine.

Sure the CGI was distracting and unnecessary in many, many cases. The worst CGI stuff was speeding up or reversing dance moves in a way that looked very fake.

I think J Hud was good, so was Ian McKellan, and the woman who played Victoria. James Corden and Rebel Wilson did their normal shtick and they were good enough.

I think it was fine - but a more traditional kind of film-making where you place a camera in a spot and watch a great dancer uninterrupted for longer than 3 seconds would have served the material better - in the same way a Hong Kong made Jackie Chan film has minutes of stationary camera during a fight scene, where a Hollywood production cuts so often that you lose track of the action spatially (and sometimes chronologically.)

It was fine - I think theater nerds might get more pleasure out of the screw ups - but I don't think it's bad enough to get a Rocky Horror Picture Show audience participation movement going for longer than a few months.
