I was not impressed by the acting of the lead character; but I was impressed with the way that they got across the background forces that allow such situations to be perpetuated unchecked: fear of loss of jobs; fear of stalled career progression etc.
Having dealt with a ward situation not dissimilar to the one portrayed, when OH was in hospital with a fractured femur, I fear that the problem is widespread. Like the family on the TV, we stayed with him almost 24 hours a day to ensure he was fed, hydrated, given pain relief etc.
The hierarchy of fat cats administering the system is a shocking waste of money.
And as for the complaints system......don't make me laugh!!!
I felt the film portrayed accurately some of the basic problems in the NHS; and also the rogue burnt-out members of staff who lack compassion. I so identified with the daughter's initial diffidence in trying to talk to staff: one part of you recognises that they are overstretched, but the other fears making things worse by intervening and speaking up.
The scenario of food out of reach rings a big bell with me. The problem is that if you try and complain, the paperwork on the ward looks good: e.g. it says they got a dietician in, and that a suitable diet was available, etc. etc. - but it does not say the patient could not reach it.
I do not pretend to know what the answer is, but I do know that when I worked in the NHS the atmosphere of dedication and teamwork shone out - that is now missing in many places.
