Not your "average" Time travel concept being addressed... This film introduces some very interesting metaphysical, moral, and emotional related concerns. Some folks do not like the female protagonist because of her actions, yet it does not seem like people are taking into account how "emotions" factor into the equation. No matter how smart someone is, grief, anger, regret, and the feelings of helplessness come into play. This is a great film for anyone wanting to dialogue about any number of topics this film addresses and there are many that can be discussed!!
