Good luck with the operation - I am a bit wary of what MB might do - it makes no narrative sense whatsoever - it might send you crazy in hospital!
Indeed when I wrote the back of pack (back in the days when I tormented consumers with madness) I freely admitted it made sod-all sense but I would maintain it's got great atmosphere and isn't boring and feels almost like Fulci having a clear out of his cupboard of madness and just flinging stuff at the screen until he runs out!
Actually you'll probably laugh yourself better! I'd also be tempted by The Frightened Woman although it may prove a little too stimulating
and rupture something!
Hope the op goes well
