It is based a typical love story from Hollywood, with a story that was well told a thousand times. The special feature here the disease Alhzeimer, and that is, I think, shown overall harmless and understatement. Certainly, represent the real disease as possible, would be too sad for a cozy movie night and the end of the film would not work anymore.
Nevertheless, I have no regrets to have seen the film. The actors I thought was great, the atmosphere is rendered perfectly by the corresponding images and sounds.
If you like those kind of movies principle that makes here certainly nothing wrong.
