Watched it because of the monumental undertaking these people had filming it...but in the end, I found the movie pretty boring and kind of cliche. I mean sure, unless you raise some kind of really gifted children or the next Charles Manson, most regular, everyday family stories will be a bit mundane, but this one, because of what they were trying to portray with the time line, just felt so redundant. I did like the way it represented the mom, who just had really bad luck in choosing men, but in the end she accomplished her goals (in terms of school and stuff)...Patricia Arquette is a great actress and she certainly showed this here.
Ethan Hawke seemed like a shadow in this story...and I guess for good reason, his character was the divorced father who just pops up here and there to try and be a part of his kids life. I could really relate to the kids in this situation because my dad was similar...just forcing the issue, instead of enjoying the time they had together, he tried to fill it with being a half father half friend, which was mostly just annoying.
A lot of people reviewed this movie saying they felt like they were part of the family at the end, but to me, I couldn't feel much more than just a creepy observer really, watching their lives play out on "hidden" cameras (for lack of better term). To me, it didn't live up to the hype, but I have to respect the investment...I can't imagine such a long undertaking.
