The film has a solid, touching story at its heart, good actors, but has painstakingly slow pace that will unnerve many viewers. I give it a 7, but I feel it more like 6.5 - it has faults that keep it from being much better.
I personally like slow films, but this one was tedious and very boring for me at times, mainly because scenes are stretched out to the maximum, dialogue is sparse, in some scenes non-existent. Characters go through a lot of daily mundane tasks, with the same monotonous pace as they will later dive in extraordinary ones, which kind of makes it same-same and takes the edge out of its story.
It's probably directorial decision to make it like it is, to show the titular "Alienation" in the characters and times, but it is a decision that makes for bad and unnerving viewing. One can't help but think that if the authors had inserted more material in their film, added a bit more revealing dialogue, even if sparse, and even some faint music to the slow long nothing-happening scenes - they could've kept the alienated atmosphere of it, but achieve more tight and enticing film.
As it is, this film will be favored by the most patient of viewers only.
