Misbehaviour is a great, reasonably balanced if a little formulaic comedy drama that's funny and relevant. Keira Knightly and Gugu Mbatha-Raw are both incredible. Jessie Buckley, Rhys Ifans and Greg Kinnear are all great. Philippa Lowthorpe's direction is also great, it's well filmed and well paced. The music by Dickon Hinchcliffe is really good and the soundtrack is good.
