The best plays of the decade are: The Curious Incident of the Dog in the Night-Time and Billy Elliot

Lengthy titles bear lengthy titles.

The Curious Incident represents contemporary children's theatre of the last few years. Billy Elliot represents a classic drama which is universally relative.

Back in 2005, Billy Elliot the Musical premiered on the West End by Lee Hall and Stephen Daldry based, of course, on the Oscar-nominated British indie starring Jamie Bell. It tells the infamous story of a Durham lad at ends with his family about pursuing his dream of becoming a ballet dancer.

In 2012, The Curious Incident premiered on the West End by Simon Stephens based, of course, on the Man Booker Prize nominated novel by Mark Haddon. It tells the story of a Swindon lad at ends with his family and his Autism spectrum condition about investigating the death of his dog.

Both Billy Elliot and The Curious Incident the plays capitalised on the immense success of their originals and went on to extend the worlds they created exponentially. Billy Elliot the Musical cost £5.5 million to make on the West End - £3 million more than the film did. On Broadway it cost more than three times the film's budget.

Billy Elliot's appeal lay in the strive to chase dreams when surrounded by adversity. The Curious Incident's lay in a meta-narrative treatment of a character account seen through its character's Autism spectrum eyes. Billy Elliot still goes strong and will premiere in Sweden in 2016 and The Curious Incident is still in its infancy and will premiere in South Korea - only its third territory - in 2016.
