The thought is interesting and the message, beautiful - life isnt a series of calculated events so seize the moment. True happiness lies in the smallest of things. However, the films reasoning is flawed. Unlike movies like About Time, which have explored the fantasy time travelling theme with much heart, this one uses it as a punishment to conform the man, who is devoted to his ambitions. You dont see anything wrong with his choices to begin with so his change of heart doesnt tug at your heartstrings either.
