Wonderful, underrated film
I just happened to wander across this dvd on Amazon and picked it up, assuming it would be quite ungood, as most end-of-the-world films tend to be. Wow was I wrong - this is one of, if not the best end of the world film I have ever seen.
As others point out, it's not about the WHY of the end, it's about people and their reactions - a real look inside of people's hearts and minds, slowly revealing their innermost thoughts and building to a most beautiful ending.
The performances are wonderful, especially Sandra Oh, although everyone did a fine job and the film really brought me in. And the writing - how all the stories meant something... I was shocked and delighted. I won't say more so I don't spoil it, because I hope more people will discover this fantastic film for themselves.
Also I should mention the dark comedy in it is brilliant, everything about this film really won me over. I only wish it had been more successful. If you haven't seen it and appreciate great writing, acting and a fascinating story I do highly recommend this.
