This is a 2006 production that I just happened to watch on Popcorn Wednesday this evening :P
Some critics had gone on and on about the inconsistencies and the logic and time paradoxes. Whatever! Grossing USD 13.6 million in its opening weekend simply shouts- "We viewers LOVE it!".
To a romantic, like me, it's a definite two thumbs up! The chemistry still exists between Keanu and Sandra since Speed of 1994 and it plays a big part in moving this story.
When viewing, concentrate on the emotions and situations arising. The relationships (not just between the two main characters only, the supporting characters add more flavour to it), the hoping, the desperation, the frustrations, the disappointments, the love.
Don't get too distracted though, you'd need to be alert enough to be marginally aware of the timeline and time difference to appreciate what the main characters are going through.
Though it seems to be a no-brainer, but it kept me just slightly off-balance to be unsure if the ending would be happy or sad. It is light entertainment with enough of a twist to keep it interesting.
To other romantics out there, if you haven't seen it, do give it a try.
