It took a while to get going, for me, but this is a film where the audience clearly gets reeled in as much as Phoenix's character does, and as such, the few twists and turns the film takes really keeps you engaged.
Maybe it's because Theodore (Phoenix) is in a place that makes him feel isolated, or simply because of the nature of 'Samantha', but the film does a fantastic job of making you feel as lost and withdrawn as Theodore's character, which in itself is a mean feat.
I'd say Samantha could be voiced by a fair few actresses and still make the character work, but Phoenix is excellent and he basically makes the film.
There's one scene near the end where I felt the film could have ended, and would have left an even more intense feeling with the audience, but it all works well anyway.
8/10
