TBF to DEH it had a good run for an original musical with productions around the world, the movie didn't help but I think it would closed anyway, likewise with Come From Away which closed around a similar time as DEH.
With Cats, the movie sucking and failing won't kill interest in it. It's one of those shows which excels on the stage. I'm really want a Miss Saigon movie simply because it's one of the few musicals which is very cinematic in its staging. The Book of Mormon which I do like would be harder to pull off as a movie.
