This is a brilliant feature but its also a heart breaking one, viewers who are expecting a feature such as meet the fockers or something similar to this genre would do well to think again.
Instead I found that this film was more in tune with Clint Eastwood's Gran Torino, the characters a very different but the theme of aging and the trials and challenges associated with it are strong.
De Niro's character is an aged father of grown children whose hopes of family reunions being perpetually frustrated goes in search of each of his children paying them surprise visits. In the course of which he discovers that they are not all being honest with him or, in some instances, themselves and that they are dealing with disappointment, disaffection and confounded expectations too.
Characterisation is done very well, the cinematography is good too, often evoking feelings in the viewer without overbearing narration or similar plot tools. Instead there are brilliant scenes in which De Niro's character sees his grown children as they where when they were younger or dream sequences which combine wish fulfilment (the hoped for reunion) and revelatory ephiphanies (like Jungian dream analysis put on screen).
There are some incidential but brilliant touches, the kindness and respectfulness of an older generation comes up against the feelings of aggrieved entitlement of another, the pictures taken throughout are taken with a film camera and then appear as the credits role along with other photograph memories.
Overall it was a good feature and I felt would bare rewatching a few times but it is also a very saddening one, despite its ultimately happy finish and upbeat scenes. Extras included on the DVD include deleted and extended scenes and an interview with Paul McCartney who talks about writing a song for the film (this was a bit odd I thought but anyway). Recommended.
