I think that this film is extremely thought provoking. It questions the accepted norms for love and is more than just a regular sci-film we have come to expect over the years.
The film has a great storyline and superb acting done by Scarlett Johansson, Joaquin Phoenix and Amy Adams.
Overall, I think Spike Jonze has created a masterpiece of a film — one which will no doubt achieve legend status among cinephiles and critics alike.
