This film is really a must watch. It is not as sappy as you think. Initially, I had to be persuaded and dragged to the cinemas when I was told that this was a rom-com. But when a young man came alone and sat beside me in the cinema, I became rather curious; usually guys would be dragged in by their girl friends just to watch a rom-com! Boy, was I wrong about the film and am thankful that I didn't miss it. It is NOT just a rom-com! It's a beautifully told, warm sci-fi dramedy about ... time! Time we could have and should have used better. About fathers and sons! About family. [No wonder the young man beside me wept during the last act of the film.] The brilliance of the film lies not so much in the narrative, but in the casting - especially Domhnall Gleeson in the lead role as Tim Lake the son, and Bill Nighy as the father. The choice of the Domhnall Gleeson has proved to be a stroke of genius. Established in the UK as a brilliant comic actor having earned a Tony Award nomination in 2006 for his role in "The Lieutenant of Inishmore", he deserves full accolades for carrying this film. When Tim turns 21, his father reveals a family secret to him that the men in the family can travel through time! Just like Peter Parker, if he had so much power, what would he do? To his father's consternation, the geeky, awkward Tim only wishes for one thing - use that power to get a girlfriend! It gets hilarious and silly as he pursues that quest while beginning adult life in London as a lawyer. Rachel McAdams is predictable in her role as his love interest. As the story unfolds, Tim is challenged constantly by the need to correct his mishaps only to realise that there's a price to pay in trying to change the past. The narrative is uncomplicated, but there are fuzzy and untidy bits in the script that will leave you frustrated. However, the likeability of the cast, the believable portrayal of the characters, and the strength of the values from this film will leave you strengthened in living out the realities and sorrows of life. I left the cinema having genuinely enjoyed myself, leaving the young man who remained seated in deep reflection. In the end, living life fully is really about time. Making the most of time because it really is precious.
