The Batman was good. A little long for my sensibilities, but that's fine. There's a lot of chatter online about how this movie is a masterpiece for this reason or that. I didn't see any of that. It's a good take on the character but here's the thing, I've seen every Batman movie in the theater. And while I've enjoyed most of the them, do we really need more Batman movies?
I hadn't seen Dune when it first came out because a) the 1984 version made zero sense to me. b) I've never been able to get into the books. c) It has Tim Chalamet in the leading role (I can't stand that kid.) BUT all the online chatter with this one was about how it is a true cinematic experience. The cinematography paired with Hans Zimmer soundtrack make for a unique experience. So when the movie came back to the theater for the Oscars I made sure to get out and see it.
From the first second Dune opened I was instantly alienated. Even though the settings aren't necessarily foreign, the politics and the religion/beliefs are very "other." The creatures and costuming helped to make things feel foreign as well but ultimately it came down to the music. Many times I wasn't sure what was supposed to be music and what was something happening in the environment of the movie. (It reminded me of Arrival in the that way.)
I enjoyed both movies equally as far as story goes but Dune pulls ahead precisely because it felt like a new experience. There is nothing in The Batman that was surprising or new. Gotham is crime infested and only the troubled Bruce Wayne can fix it. Dune truly felt like I was transported to another reality and THAT is why I read books and go to movies.
There's a great video on YouTube with Hans Zimmer talking about how they made the music. If you like that kind of thing, I highly recommend it.
