I thought it was very well done.
Personally I ended up bawling my eyes out before I knew it, because the old lady who thought the lad looked like Prince William looked just like my nan, and was acting just like she used to, too, all sweet and flirty-like. ('I'm putting you to bed now...' 'Ooh, aren't I lucky?!') Sob.
I wish more carers were like the woman who was training the lad called Jace I think it was - she seemed really good at getting him to empathise with the residents when he was feeling uncomfortable. She's the kind of person I'd want looking after me in my old age...
