What makes poetry a special art form? Answers might include bringing together extremes of joy and despair within a couple of lines, offering an alternative to rational thought, enriching our outlook and understanding in ways that prose would struggle to equal. Poetry can provide a single phrase or sentence that is easily remembered and somehow unlocks difficult-to-express inner states, just as a song can (and poetry is the basis of songs). It offers a freedom of expression where you don't need to explain every aspect of what you are saying - it urges the listener to grasp a semi-spoken truth or idea.

That's my rough guess. I've got over 40 books of poetry on my bookshelf at the last count, yet I'm no literary expert and appreciate poetry in a very simple way. Most people might agree that poetry offers something special, so a film celebrating the life of a famous poet might be expected to bring us a glimmer of that something.

Sylvia Plath has been championed not only as a poet but as a sort of ‘feminist' – a cry on behalf of women treated as a commodity, subjugated by an unfair male-dominated system. Cast in the lead role, Gwyneth Paltrow's Plath focuses much attention on how downtrodden she was, chained to two children, overshadowed by a brilliant and celebrated Ted Hughes, struggling with bitterness, jealousy, mental instability and a less than attractive persona. We also get the occasional poetic outburst, from who-can-recite-poetry-fastest undergrad shenanigans to romanticised performances of Chaucer (addressed to an audience of watching cows whilst floating downstream in a boat). All punctuated with soft-focus shots of a naked Plath/Paltrow, hysterical and often violent outbursts at Hughes, and scenes of a generally uninteresting and uninspiring life of moderate wretchedness. The only thing that distinguishes Sylvia from the now-unfashionable kitchen sink drama is that its central character is called Sylvia Plath.

So is the film worthy of the title? In A Beautiful Mind, we learnt of the joy of mathematics, Lunzhin Defence championed the addictive mysteries of chess, and Dead Poets Society made us lift our eyes to literary horizons that could inspire the dullest of minds. Sylvia was limited, perhaps, by the refusal of her daughter to allow much of Plath's poetry to be used in the film but, for whatever reason, it has failed to be more than a rather humdrum biopic. It offers little insight into her poetry or the magic of poetry generally, and adds little of interest about the historical figure that doesn't apply to millions of women. If any deep philosophical statement can be drawn from this, the film certainly doesn't make it, poetically or otherwise. Sadly, it would seem that the words of Sylvia Plath's daughter almost became a self-fulfilling prophecy: "Now they want to make a film . .. They think I should give them my mother's words . . . To fill the mouth of their monster . . . Their Sylvia Suicide Doll." Whilst not quite an empty doll, Sylvia is maybe an arm or leg short of a manikin.

Once Ted Hughes died in 1998, it became open season to speculate as to what had happened in his short stormy tempestuous marriage with Sylvia Plath. Some people blame Hughes for Plath's suicide in 1963.

The film begins when American Sylvia Plath (Gwyneth Paltrow) a Fulbright Scholar at Cambridge University where she meets acclaimed and passionate Ted Hughes (Daniel Craig) a man who lives for poetry.

They quickly get married and initially move to the USA. Plath finds it difficult to write and Ted feels uncomfortable in America. They return to Britain, but Sylvia struggles with Ted's infidelity, his success as a writer while she raises two young children.

However in time Sylvia starts to develop her own style of poetry which is based on her personal moods and state of mind.

Craig gives a passionate performance as Hughes, he comes across as fiery, talented and a ladies man. Paltrow has a more difficult role as the vulnerable and neurotic Plath but she does well with what felt was an underwritten role. The film makes it clear that Plath had bouts of depression and even attempted suicide before she met Hughes.

Sylvia cannot get a handle on the complexities of the characters that it is dealing with. In the end it treads a middle line neither blaming Hughes for Plath's death or absolving of any responsibility. The film does feel flat and undernourished. It was not helped that the Plath estate would not grant permission for the use of her writings in the movie.

It's 1956 Cambridge, England. American student Sylvia Plath (Gwyneth Paltrow) is dismissed by the high-minded poetry review. She is taken with fellow student Edward Ted Hughes (Daniel Craig)'s poems. They eventually get married. He has many female fans and she suspects his infidelity. They have two children. She struggles to write under successful Ted's overwhelming shadow. She falls into depression and eventually commits suicide in 1963.

It's a downbeat biopic that bothers on old-fashion melodrama. Paltrow is lovely but I figured Plath would be more fragile even before her breakdown. Daniel Craig has the prerequisite charisma. The movie is very flat. It is unable to elevate the material into something more dramatic. This is a long drawn out character study that isn't terribly interesting.
