Bruno Babic’s review published on Letterboxd :
First of all: It's a true drama, not a little boy's fun adventure movie.
I felt some great potential while watching it, but so little of it was actually used. The characters are OK, but since it's all about the boy, none of the other characters feel like they have any real depth. It's an OK movie, at times maybe even heartbreaking and depressing, but it's not a spectacle I was expecting it to be. Lower your expectations a bit and you'll probably enjoy it.
