The concept is interesting, but the film lacks emotional complexity. Not terrible, but they missed a good opportunity for a beautiful film ultimately about love. With the exception of Rosario Dawson, the film doesn't have characters with enough depth for the audience to genuinely care about the final outcome of the movie. Will Smith is capable of amazing work, and he has several nice delicate scenes of rage and sadness, but overall is feels like a performance that was Oscar bait. For a movie about grief, love and redemption, there are too many surface level emotions created by an extremely talented group of actors. The director needed to pull more out of his actors for this ending to be worth the journey. Without that emotional depth, the end of the movie almost seems misplaced and unnatural to the rest of the tone throughout, like it's trying too hard to make you feel something instead of actually feeling something.
