A emotional movie which doesn't generate enough emotion

Rating: 8/10 (5 October 2017)

After realizing he agreed to completely erase his life partner from his mind, Joel finds himself in a terrible situation. Remorse comes into action, reaching the point where he struggles to keep her memory alive, while reliving and sometimes altering memories in which she was present. Unfortunately, as he struggles, many failures start piling, but all seems in vain, although he's desperate to cancel the procedure.
A movie with a plot like this one is almost guaranteed to be a success but this one wasn't able to leave me a remarkable impression. It has tension and drama but it lacks emotion, and a movie in which you don't feel almost anything for the main characters, cannot be fully enjoyed it as you should. I don't quite know if the presentation or the characters are to blame, but they weren't able to create an emotional atmosphere which should keep you eager to find out its finale. As with many movies, it had a brilliant idea which wasn't fully exploited by the producers, thus leaving a dull sensation, even after its ending, which wasn't as conclusive as I hoped.
