You may not know about it yet - it's tres underground after all - but there's a relatively new style of film-making that's making not so much waves exactly, but perhaps a splash or two. It's called Mumblecore, or just Mumble movies to its friends.

Essentially a mumble flick is one that finds much of what the cast say almost inaudible at times, delivering mundane dialogue about their mundane lives. Oh and would you believe it, they're made pretty much on the cheap too.

Lena Dunham's Tiny Furniture certainly ticks all the above boxes.

There's no great welcome home for Aura on her return from college where she's just graduated. Her mum Siri (Laurie Simmons) is a photographic artist who is consumed by the projects she has on the go, whilst her younger sister Nadine (Grace Simmons) is disappointed at having to give back her sister's bedroom.

She's happy enough though, as she's just glad to have some family and friends around her after a rough break up with her boyfriend.

To get her mind of off things, she decides to get a job. Not like a proper job-for-life kind of job, but something to just bring a little money in.

Her eccentric friend Charlotte (Jemima Kirke) tips her off about a job as a day hostess at a local restaurant, which she applies for and gets.

It's not long before Aura starts to seek male attention again, but the attention she gets back isn't quite what she had in mind.

We need to document this moment, when the giants decided to finally take over the Earth!!!

So, Dunham not only stars in this feature, but also directs and writes it too; that's not bad going for a new kid on the block. And off the back of this film alone she's managed to secure a TV show on HBO called Girls. Whether this film warrants it however, is difficult to say.

The acting has to be considered loose at the best of times; it has a sub-indie feel about it that leaves you feeling that perhaps the cast just aren't really trying that hard. But then that could just be a curve ball thrown from the dialogue; yes, there is a lot of mumbling, and much of the script appears to be born out of the banality of reality, but it just doesn't make it that entertaining.

Dunham isn't your archetypal leading lady, but that's not necessarily a bad thing. She does however, possibly spread herself way too thin when it comes to all the hats she wore on this project. If she focused on just one element she could possibly excel, but acting, writing and directing is clearly just too much of a stretch for her.

The characters she has written, for example, have absolutely nothing engaging about them. They're the type of people you would happily ignore in the street, and certainly not the type you would strain to eagerly hear what they were discussing in a coffee shop. They're nothing more than dull characters in a dull scenario with nothing to say. If HBO saw this as cutting edge observational material, they may well be losing the plot.

Does it stand out for being different? Yes, but not necessarily in a good way. To make matters worse, it has one of the most flat, unsatisfying endings to any film in quite some time. Of course film students wearing black berets dissecting it would no doubt claim it was brave, but that only shows them off for being the complete tits that they are.

Tiny Furniture is one of those films that has enough about it to make you curious enough initially to see, but ultimately makes you sorely disappointed for doing so.

If nothing else it proves the Mumblecore is less a movement and more a pointless distraction.
