Yeah, I liked the way they didn't really try to sugarcoat that. I really liked the design of the minds of the insane.
Gloria's mind was done very well considering she's bipolar - they brought her past together with her illness, for what sort of world she lives in. With Boyd, he's a paranoid guy who believes in conspiracies... that was done excellently, in my opinion.
I like how it doesn't belittle insanity. With Loboto, it's a comedic view of an insane guy, I think, but it doesn't go, "and this isn't important", it just adds humour because frankly, he's in some scary scenes, and the humour covers over that - like the dialogue in the scene where Loboto removes Dogen's brain.
