The camera work and editing are brilliant, and it feels much more modern than I would expect of a film made in 1963.
Unfortunately it was lacking in other aspects. Resnais has a very distinct style that worked with Marienbad and Hiroshima, but for some reason it failed to capture my attention the same way the other two did. Perhaps it’s because I felt detached from the characters. Whatever the case, Muriel felt a tad dull, not having the emotional impact of Resnais’ two earlier films.
