Oh gosh this thread is soul destroying.
Firstly, as a sister working on a busy unit I'd be really disappointed in our staff if they were watching a programme on the ward busy or not - it's not professional. On breaks, at quiet times away from patient areas I'd turn a blind eye but not on the ward or if there's jobs to be done. So no OP I don't think you're being unreasonable in this case.
However I do agree with the posters who say that without having done the job it's very difficult to understand the pressures of the work. When I became a nurse I admit I didn't really know what the job entailed - it's much more responsibility than what I expected and so much falls on our shoulders. There's a lot of hidden work goes on that people just aren't aware of and whilst It would be lovely to update patients on what I've been doing behind the scenes every couple of hours it just isn't feasible.
I have no doubts that when I've sat at the desk writing my care plans, doing online referrals, chasing bloods, x-rays and scans, chasing doctors to review bloods, x rays and scans, ordering meds for discharge, organising care packages and transport for discharge, answering the phone to relatives and admitting patients I've been looking upon as the lazy nurse whilst the HCAs are doing the care/obs. However if I didn't do all of those things, nothing would move and no one would achieve anything from their hospital stay. Not to mention I could be in big trouble for not doing any of the above properly resulting in unsafe care.
I most definitely have compassion fatigue. When I first started nursing I was lovely and assumed all patients were genuine, however after years now of being spoken to like shit 70% of the time it's worn me down. I know people are anxious, vulnerable and in pain but that goes for most people in hospital and unfortunately we have to prioritise. I'm also really desensitised to distressing situations and whilst I try and maintain my empathy most of the time, i do feel frustrated when someone is wailing about something reasonably minor which is preventing me from getting to my end of life patient who needs anticipatory meds in the next bed.
I probably come across as slightly cold sometimes but personally if the roles were reversed I would rather my nurse got things done and sorted for me and kept me informed rather that taking valuable time to make small talk with me. I've never won any awards for compassion but have been promoted for my efficiency and I'm ok with that 
Most of our complaints aren't about nursing staffs behaviour but about waiting times and other things beyond our control. The shortage of nurses is one thing but the Drs staffing is another. Most of the time things come to standstill because we're all waiting on one poor registrar who's been in theatre for the last 7 hours 
but the patients see us sat down and assume it's because we can't be bothered that nothing is happening. I'm proud to see I feel I run a cracking team, very rarely would we ever have a situation where a patient isn't turned, fed or cleaned when needed. I've had multiple shifts recently where my staff haven't had their proper break and barely moaned about it just so we get through the day/night safely. It's always escalated to senior levels but what can they do about it? We can't magic up more budget and staff.
Unfortunately the NHS is what it is, and I feel increasingly that it is a tough place to work on the front line but in the OPs defence it's no excuse for laziness or unprofessional behaviour.
