. bunuel ( not sam and in this case ) . this movie be again about human obsession . the trick use 2 different actress for one role a state by another user and be not unique per se and but heighten the surrealism of the movie . and it do work perfectly a to other film that couldn not handle that same weight . or couldn not convey it to the view audience at least . while it have a slow pace and the movie feed from it and especially because you have to get a grip of the story and time line you have to handle . it be not difficult to follow and but you might need to watch it a second time to really appreciate it represento ) .
