I really like Anderson, and even his most arch moments tend to not bother me.
Asteroid City, similar to the French Dispatch, however, feels like an experiment in style over substance. I won't spoil the film, given you've not seen it, but the framing device really didn't work for me. The characterisation, which is great in his best work, falls flat here. Because of that, the main themes of the alienation of grief and not fitting in, which are present in all of his previous films, don't land as effectively. It's sort of a study of the process of creativity and expression of self too, and whilst that's also not new territory for Anderson, the framing device, the principle cause of my feeling of disconnection, is a big aspect of this.
I didn't dislike it at all. There's a lot of great shots, the acting is good, but it doesn't quite work for me. His last two movies have crossed into territory that nullifies the undeniable charm of his best works for me. I can see how they illicit strong reactions, even more so than his older work.
I'll watch it again someday for sure, however, if only to see if I view it differently.
