I must agree with the other reviewers in one respect, that is, all the players play their parts really well and make this film watchable (just)!
Unfortunately this film suffers from the same problems as "Myra Breckenbridge" for instance, that is that the author of the novel (which is great), also made the film, and Boogie Woogie proves once again that good novelists very rarely make good directors, especially when it relates to their own novel/s.
The other glaring problem, is that male directors never shoot scenes of sexual activity between women and make the said scenes work, the scenes always end up either as "soft porn" or, as in this case, the women look as if they are going through the motions, and not enjoying making the scenes.
For me this could have been a very good film,instead it ends up a mess, plus I also think that Ms Lumley and Ms Anderson are under used! Rent don't buy!
