But as a fan of the book I was left disappointed by what PS I love You had to offer.

PS I Love You is a romantic drama starring Hilary Swank as a young widow who discovers her late husband has written a series of letters before he died to help her grieve.

Swank plays Holly Kennedy, a real estate agent forced to come to terms with the unexpected death of her young husband Gerry (Gerard Butler) to a brain tumour.

On her 30th birthday, her mother Patricia (Kathy Bates), arrives with her two best friends Sharon (Gina Gershon) and Denise (Lisa Kudrow) and a birthday cake from Gerry arrives with a tape recording.

This tells Holly that he has written letters to help her through her grief that will come at various times, from various sources, without warning.

When she begins to get letters from Gerry, it slowly helps her get her life back on track - from telling her to buy a bedside lamp, to sending her on a trip to Ireland.

With each letter comes a new adventure, and something new to master to help come to terms with her grief.

It's only as Holly comes to realise that her friends' lives have moved on - Sharon has a baby, Denise gets married - that forces her to wake up to the fact that she's remained emotionally static since Gerry's death.

Inevitably Holly comes in contact with other men - from Harry Connick Jr playing Daniel the bartender - who couldn't be any less like the character from the book if he tried - and manages to say anything and everything that comes into his head, no matter how insensitive, to Gerry's childhood friend William (Dean Morgan), who she bumps into on the Irish holiday - who doesn't even feature in the book.

Ps I Love You is a good film. And if I had never read the book, I would no doubt have loved it.

But, it bears little resemblance to the novel - set in New York rather than Ireland, and rather than Daniel being the character we come to know and like in the book - he comes across as gawkish and irritating, and even Holly isn't as easy to like in the film as she is the book.

But that aside, it will have you weeping all the way home, and wanting to tell everyone you love just how much you love them.

Good film, but nowhere near as good as the book.
