'Frozen is not a book!' - Consternation on Twitter as Elsa costumes take over #WorldBookDay
As anyone who has gone within half a mile of a school will know, today is World Book Day, and children in the UK and Ireland have been encouraged to dress up as their favourite book character.
However, many children appear to have begged their parents to go dressed as their favourite character full-stop, resulting in a plethora of film characters alongside the Where's Wally and Harry Potter contingents.
One has made her presence felt more than the others.
On social media, annoyance over Disney's all-conquering film Frozen taking over World Book Day is threatening to trump the irritation over children dressed as comic book characters.
Comic book characters should absolutely count as being from books! Wait, wrong argument. Moving on.
The debate on whether Elsa and Anna should feature at all on World Book Day has split people into three camps:
Camp 1: "Frozen is a film! It bears about as much resemblance to Hans Christian Andersen as Sebastian the Crab does to The Little Mermaid"
Camp 2: "Frozen is based on Hans Christian Andersen's The Snow Queen, a totally legitimate fairytale"
Oh, and by the way Disney has turned Frozen into several books now so...it sort of counts?
Camp 3: "Seriously, who cares. Have you tried to wrangle a small child of iron will into a costume lately?"
It isn't only Frozen which has inspired a creative take on what counts as a book. Jeremy Clarkson from "the Top Gear book" may well be our favourite costume of the entire day.
Many parents were thrilled that their children decided to dress up as characters who weren't from Frozen.
Really, as long as your child reads, and is happy, that's all that matters.
