This movie starring Blake Lively entails a Benjamin Button esque storyline. She is unable to age.
The film is definitely worth a watch however don't expect any academy award winning acting or storyline. This feature plays on an old adage, "What would it be like to never age?" All of your friends, family, daughters etc. would all be dead while you're still only 25.
It is an old idea with a more modern feel. The atmosphere is definitely impressive for the scenes and times.
