A romance for your mind.
I was a little iffy about seeing this movie until my girlfriend (19) swayed my opinion about it and took me to the theater (I paid!).
At first I thought this was going to be a too-serious, heart-wrenching movie about a long distance relationship- only it wasn't. It was almost the opposite.
There were no drugs, sex, or anything objectable in this movie in my opinion; the drinking was far less than any child would witness at a family get-together (assuming wine or any other alcoholic beverage is present.)
The reason I WOULD NOT recommend this to ages <13, or even <18 for that matter, is not because of objectionable content, but only because of the storyline. If I had 13 year old children, they most probably -wouldn't get it.- I have rated it PG-13.
The space-time concept in this film challenged my mind more than the romance challenged my heart, and as a result, I would even recommend this movie to guy friends of mine.
This is a simple love story with an incredible time twist that will keep you thinking and saying "what if?" hours after the ending credits.
