The Working Title rom com done in America, though it still feels very English - so much of the humour comes from embarassment and awkwardness (Ryan Reynolds being busted with toilet rolls and talking to his young daughter about sex, sexually confident female leads), and there are some scenes that feel so English (a love poem to smoking).
I like Reynolds as an actor and as a star when he's doing his sarcastic thing. But he seems uncomfortable playing a shy Everyman - it's a role that needed Hugh Grant or someone more boffin-y. He's kind of a nothing. Kevin Kline is fine in his colourful support cast but you know someone like Bill Nighy or Rhys Ilfans would have knocked it out of the park.
As the trio of girls, Elizabeth Banks, Rachel Weisz and Isla Fisher are fun and beautiful and Abigail Breslin does what's required as the girl. I enjoyed the passage of time stuff, hated that Reynolds took so long to give the book to Fisher, the support casts and Bill Clinton stuff always felt like it was going to do more than it did; it's good (if that's the right word) to have a movie acknowledge the pain of divorce. This wasn't perfect, but it has charm and it lingered in the mind.
