Jane Nichols (Katherine Heigl) has been a bridesmaid for 27 of her friends, but never the bride.

Sorting out everything from the parties to the place settings, her inability to say no has left her with nothing but a closet full of dresses.

But when her boss (who she has been silently in love with for years) announces he will be marrying Jane's little sister, this is one wedding that may test her unquestionable desire to please - especially with reporter Kevin Doyle (James Marsden) interfering.

Actors and producers are notorious for making the leap into directing, but Hollywood choreographers are slightly less common.

However, don't let this allow you to think that 27 Dresses helmer, Anne Fletcher, is any less able to bring a well-rounded and solid romantic comedy to the screen.

Ticking all the necessary boxes of complicated action, moment of revelation, self-discovery and 'reach for the tissues' conclusion, the film certainly won't be winning any originality awards.

But it isn't meant to.

The stock characters comprising loveable but down trodden protagonist with an unrequited love, the antagonising but charming man to show her what she needs, and an assortment of quirky support including a self-absorbed sister and funny/slutty best friend may round off a very average pitch; but thanks to the right actors in the right roles, the chemistry certainly works and makes the film stand out.

Knocked Up's Katherine Heigl shines in a title role, managing to bring an 'everywoman' quality to the character without it seeming too contrived and unrealistic (in the pseudo-reality of rom-com land).

But it is James Marsden who manages to pull of the real coup d'état as love interest Kevin Doyle. Carefully straddling the line between irritatingly charming and just plain smarmy, he brings the laughs and love in equal measure.

Able to appease the target female audience as well as maintain enough interest for any men in the crowd, 27 Dresses happily balances sentiment with sincerity and humour to make a very watchable 107 minutes of romantic comedy.

7/10 - Highly predictable, but still entertaining.
