I think one of the things that annoyed me most at the start is what makes this book great. The narrator turns 5 at the start of the book and the viewpoint is very much that of a small child. After a while, you start to ignore the poor grammar and the world as told by Jack becomes absorbing. I guessed the reason they were in Room pretty early on but it is a very unique view and very well done. May not be everyone's cup of tea but 5 stars for being different.
