Having not read the book that this movie was based on, I have to say "I want my time and money back." The message this movie was trying to convey was nice and all, but not enough to make me feel good about witnessing the hour and a half of action-less pain that the characters went through. To me it wasn't particularly entertaining, intriguing, enlightening or even moving. The Virginia Woolf part was the only believable or interesting part of the movie, everything else was full of unbelievable, unlovable characters. If you haven't read the book and you don't enjoy sobbing over idiots who are themselves sobbing about their lives instead of doing something constructive about them then spend your 2 hours and $7 enriching your own life instead.
I'll just be blunt - this movie is not what either "Mrs. Dalloway" or "The Hours" (the novels) deserve, probably just because it wasn't well-adapted. I watched, it was interesting, but I didn't think too often. And I didn't think there was any large payoff. The story takes place in 3 different time periods, the earliest of which is that of Virginia Woolf (who wrote "Dalloway"). Anything that takes place in this period is excellent, and Nicole Kidman is amazing. The farther you get from that, the more awkward it feels. Bless these actors - they're an incredibly talented bunch and I can tell they're doing their absolute best with what they're given, but some of this dialogue falls flat. Some of the lines are just not believable. Ed Harris's diction is so good I could almost picture the director in the room telling him "enunciate! project!" A man dying of AIDS in 2001 should not talk like he stepped out of proper old England ("I'twas a beautiful morning, wasn't-tit?") If you have a healthy appreciation for literature and you've read either of the books, see this as a curiosity. I don't think it conveyed the message of the novels very well - the film dwelt on present pain whereas the books' message was about the affects of the past and the choices we make. If you haven't read beforehand, The Hours (two of them, to be exact) are probably not worth your time.
