Its different. Even after hating each other, the romantic couple still find each other, still remember each other and feel the bond. The feelings are still there, Joel (#JimCarrey) specially doesnt want to lose the memories and tries to make Clementine remember. Its fast paced, but one wonders why the couple is under so much stress. Its causing mutual dislike, the common shrink? instead of patching them up, ctrl alt del their memories, in Replica with #KeanuReeves the memories are reinserted. Despite cold blooded scientific methods, an emotion like love survives. Forgetfulness is only temporary. A song, or a gesture can trigger "memories" .... just remembered its a song by #Maroon5
