Actually, the movie didn't do a great portrayal of what the disease is actually like. People diagnosed with Schiz do NOT acctually see images not there. They only hear them, or imagine them. They do not really appear like a hallucination. But I suppose being such a hard disease to explain, that was the best they could do.
I enjoyed the movie myself, even if it wasn't "great", but that movie was the thing that gave me the inspiration to tell my BF about my mother.
I wish there were more people posing here so that I could relate with others.
