The non term "comedy drama" strikes again. And since it's being used repeatedly, I'm forced to repeat my statement: "there's no such thing as comedy drama". The drama here, as in most cases when this term is used, is indeed present. But not every time humor is used the result is comedy. In this case humor is here simply to hold the drama in check and stop the entire thing from turning into a melodramatic mush. And it works, we do get a very understated and sometimes even restrained emotional reaction in a story that the normal Hollywood treatment would turn into an overwhelming sentimental tearjerker. The fact that we have no tearjerker here is in itself an achievement.
This achievement is reached with the help of the humor used here and with superb acting of all the leads. That is, in my humble opinion, what we got here is four leads and one major supporting role. Namely, Andie MacDowell, Miriam Margolyes, Sally Phillips and Rakhee Thakrar who all get their moments on screen, and Tamsin Greig, who supports this magnificent quartet. If we consider the subject matter - keeping the entire thing from going overboard is really something special that requires a lot of control and restraint from the cast. I remember seeing other movies on this topic that failed exactly in this point. The result was next to unwatchable.
One last point: one of the previous reviewers wrote the entire movie off as a collection of cliche. The story as is, without the humor and the restraint is exactly a collection of cliche. But when this collection of cliche is presented like that it becomes something completely different. For me, it became real, and touching because of this approach.
