We know that Christmas ads are all about selling brands but in recent years they have increasingly become a little part of the Christmas lead-up in themselves.
We wait all year round for the funny, whimsical and sometimes emotional ads and now, finally, one has been released.
John Lewis has struck gold in the past with Monty the Penguin, the lonely man on the moon and last year’s bouncing boxer dog. Check out the Irish connection to last year's ad here.
This year's ad features Moz, the monster under the bed. Unlike other monsters, Moz likes to play games, to offer piggyback rides and stay up to all hours with his young friend.
However, the late night antics take a toll on the young schoolboy and soon Moz realizes he must say goodbye to the fun-filled sleepovers and gift his friend with a nightlight so he can sleep better. Get the tissues ready!
People have been waiting eagerly for the ad to be released ever since John Lewis tweeted the below teaser.

Now, the reactions are flooding in and it looks like tears are being shed across the world.
Awwww I love #MozTheMonster the @johnlewisretail ad captures the imagination of childhood, which makes me feel nostalgic and is why it gets a thumbs up from me 👍🏻 but yeah it is Monsters Inc pic.twitter.com/6anejnw8Y7— Amanda Fennelly (@amandafennelly) November 10, 2017
#MozTheMonster not gonna lie, that new John Lewis ad made me cry the second time I watched it— Lucy Reynolds :-) (@Lucyis4ever) November 10, 2017
While others disagreed with the plot line, written by Academy Award-winning screenwriter Michel Gondry.
I don't get the new John Lewis ad. It's cute but makes no sense. Why was the night light needed? The kid clearly wasn't afraid of the dark or monster.— Firstplacelast😜 (@Firstplacelast) November 10, 2017

So the John Lewis ad with #MozTheMonster - once the kid gets the nightlight ... won’t he miss his friend like? Did anyone ask him if he WANTED to get rid of him? 🎄🤷🏻♀️💔— Stefanie Preissner (@StefPreissner) November 10, 2017
