OK. Saw it. Liked it a lot.
Henriksen and Mortensen are excellent in this and very believable, as far as it dares go. It's rather more aimed towards the darker in nature but lighter side of things at times, with grandpa being something of a Shock Jock and never really wandering into the harsher reality, or not, of him suffering any of the ills of true fear, confusion, rage and violent anger and the like; that dementia often brings without mercy for its sufferers. Instead, it's left to his family to recall darker memories, gasp in disgust or raise knowing eyebrows at his lines, that may challenge those of softer sensibilities, but for grandpa, he's just speaking his mind and having lots and lots and lots of nice memories - so many in fact, that you could be fooled into thinking, well, that's one worry out the way.
It's hard to take much of what he says too far to heart, as his condition relegates things and the fact that he was always an ornery SOB would no doubt have most who chose to stay in his orbit go, Oh that's just Willis. However, the grating year in and out, for the (overly?) saintly Mortensen's John, does at least reach a tepid boiling point after Willis literally forces it out of him. The sympathy really is aimed at John and not Willis but, he's such a passive twit at times and far too expectantly in the canonisation queue to feel too much for.
I'd imagine this will confuse the woke yoot of today; as to wonder what the worth is here, as they'll no doubt want to go on endlessly to explain what's wrong with the writing in Willis' views and opinions. Yeah. Really? We get it.
I did wonder if the breast shots (particularly the end one) were also what got the gay police questioning Mortensen's choice and his appearance, as perhaps it was too heterosexual for them?!
Nice little cameo for the ass Dr - who also popped up in Star Trek Discovery the other week.
