I only got around to watching this yesterday.
It was okay, it was that weird mix where you're not sure whether you're supposed to read it like a studio piece, you know? It reminded me a lot of Family Man in that respect.
Will Ferrell is stomachable in this (see Jim Carrey in The Truman Show) as usual Maggie Gylenhall shines, and she's super-hot with tattoos too. Dustin Hoffman plays the guy that Dustin Hoffman always plays, and Emma is good but annoying.
The story itself flirts with *quirky* a little too much, but is all in all, a watchable study in sentimentality.
I enjoyed it, but I think mostly cos I'm all in love and I watched it with him.
