This film had so much potential to be great, and it misses the mark.
The pacing is where the main flaws come from for me. I have no problems with a film that wants to flesh out it characters or take its time building the story, but this film doesn’t allow us to care for the main couple. I didn’t connect with them at all.
The film looks great, and is shot really well. The acting is very good too, but some of the writing is a bit off and the actually story itself is similar to a piece of bad bubblegum, sure it tastes nice for a little while, but then you run out of flavour and are stuck with a crappy piece of gum. 
Sure the element of “lamb child” is captivating and hooks you in, but it doesn’t do what it could’ve with the story.
