I'm still sobbing as I write this. The film is very good but it is quite traumatic. It is a subtle meditation on grief (as symbolised by the monster) and will ring true to a lot of peoples experiences. Billed as a family film, though I fear young ones will be too scared by the monster and too upset by the subject matter. Brilliant performance from the young lead and a great script that isn't as heavy handed as it could have been.

Dizzyingly perfect. Don't read anything about it, just go and see. Make sure you bring plenty of tissues.

I was a grown man when I lost my mother to cancer yet this took a firm grip on my heart. I can't remember the last time I cried this much at all, let alone watching a movie. And those weren't manly tears, I mean old guy full on blubbering mess kind of crying. This is one of those rare films I probably will never bring myself to watch again yet I would wholeheartedly recommend to anyone.

Decent coming-of-age fantasy fable, with the fairly interesting gimmick of using this imaginary monster to deal with grief. Ultimately I didn't care though and I think a lot of it has to do with the little sh!t, unlikable lead....

This is definitely NOT a children's film, despite the fantasy style picture and blurb. I am glad I watched this alone as my son would not have understood the deepness and heart in this movie. A Monster Calls is a hidden gem, one that I've passed over many times and wish I'd watched much sooner!
