Len Fearnside’s review published on Letterboxd:
The winner of the worst voice over in the history film. Congratulations Room. The kid was far too annoying and terrible for me to handle. Brie was very good as she always is and I liked Seamus, but that's about it. Some of the story pieces felt unbelievable to me and the score was just bad; far too cloying and even completely out of place in parts. This is one I expected to like, but boy, even two stars feels a bit generous right now.
