Some of the finest acting I've seen for quite a while. Blue Valentine is the perfect movie you want to show somebody who is going on and on about being 'madly, deeply, in love' because of it's accuracy in laying bare that all the best intentions can go awry. It's the opposite of a date movie as one memorable reviewer wrote at IMDB.
This is the first time I've seen Ryan Gosling and he is a great actor, though I'm suspicious of his Mickey Mouse club origins which is semi famous for pumping out MKULTRA celebrities. Michelle Williams is adorable as she does a little cowboy dance on their first date.
Apparently there's some debate about who is to blame for their breakup in the movie but if anything the point for me is nobody is to blame.
It's just part of life and duality.
