It isn't really a spoiler to say the film revolves around two members of a family dealing with a family death. To be honest the main premise and meat of the story doesn't really have much drama, but the acting, including the supporting actors, is good, and there is some subtle scenes which may be touching for some but really wasn't for me (and yup, I've had a family death, but nothing really reverberated here for me). All the same, I don't think there was anything particularly bad about the film. I guess it was just trying to be more of a mood piece. The way it was broken into 'scenes' probably took more away from the film than it added. It was well done and really, I think many people will enjoy it, but it will never be a classic nor is it original enough to stay in the memory. My advice is, watch it if you're not spending too much money to do so, and it will give you some entertainment value. Of course, it's a specific genre (mother angst) so not for those into action, comedy or romance. Even the backstory of this strong love seemed a bit superficial and the way it was cut into the film was sometimes jarring.
NB. Be wary of any 10 star reviews on imdb.. they seem to be fake. Definitely this film is not 10 stars, though some may like it more than me.
