The Glass Castle is a film about making big plans that you could never live up to, and I feel like this film was one of those.
The title refers to a dream house Rex (Woody Harrelson) and Jeanette (Brie Larson) plan to build throughout the story's flashbacks. Like the movie itself, the house was a very good idea. It has excellent foundations, mixing traditional with modern with the addition of some unique twists, however, for a number of reasons, the vision is never truly realised.
One of the key messages in the film, or rather a question the film poses is: is it better to try and fail, than to not have tried at all?
If we're talking about the film, I think The Glass Castle doesn't quite live up to expectations, but it still has something honest at it's centre that make it a must-see.
Perhaps they never could have made the film the way I wanted, but I had a great time watching them try, and (I'm paraphrasing from the film here, but) I feel lucky to have seen it.
