Tom French’s review published on Letterboxd :
This film is very traumatic.
Costume design left a bit to be desired. Most people spent the entire film in their swimming costumes. I think the costume designer took their job title a little too literally. Is it too much to ask to see Naomi Watts in a good frock, or Ewan McGregor in a smashing skivvy?
But otherwise an excellent film.
Actually there was also too much water, but I'm not sure how you could have had less water and maintained plot integrity.
