i think the main problem with the movie isn't the movie, it's that people are going in expecting a thriller instead of a drama. yes the major plot points could be covered in 5 minutes.. but that's not the point of drama. your average thriller is about things that happen and happen to have people in them. this movie is about the people and how they feel and cope when something momentous happens. if you appreciate that you'll appreciate the movie better, or not watch it cos it's not something that appeals to you.. and that's fair enough.
As far as the film goes, Michelle Williams carries it well. The accent's fine and the various states she goes through as she tries to deal with what has happened never feel you leaving disconnected or not understanding how she got there.
McGregor is his usual charming self, tho his is not really a major part (likewise MacFadyen), this is a movie about the mother and so these two don't get an awful lot of screen time.
The one fault i'd say is that the passage of time is not particularly well expressed particularly right at the end of the film when what seems to be a present day Ewan is wearing the exact same outfit as in the next scene which must be set sometime after.
Regardless, it's a decent movie, but requiring empathy.. so if you prefer action flicks, watch something else.
