I thought Arrival was decent.
Right up to the last ten minutes.It felt like they needed to bring the movie to a close after nearly two hours, so bam, time travel. done. There's no problem so big that it can't be solved with time travel.
Maybe I can expect this new Dune to be okay, right up to the last ten minutes?
(And FWIW IMDB doesn't seem to be confused about who directed the 1984 version. My copy lists Alan Smithee as the director, which wikipedia says is "... a common pseudonym for directors whose film was clearly taken away from her/him and recut heavily against her/his wishes in ways that completely altered the film." Not sure who to blame for it.)
