It was beautifully filmed, and several scenes were just like a painting.
I thought Jessie Buckley was good, but a bit too "full on" at times, and for that reason I felt rather manipulated when Hamnet died, and I remained dry-eyed. (I suppose it doesn't help that we know what's coming!).
But Jessie redeemed herself in the final scenes, when she dials it back a bit, and finally begins to understand her husband.
I've never seen Paul Mescal in anything before, but he was excellent in the scenes post Hamnet's death.
The final scenes, when Agnes goes to London and watches the play, were just wonderful. The connection between Will & Agnes, and the audience reaching out their hands to the dying Hamlet.... yes, now I'm crying. It was a powerful way to show us Will's true feelings about his son (even if invented) and, ultimately, a positive way to show us the power of art, specifically theatre. And that's why Shakespeare is a genius, because his plays still do this to us after 400 years..... magical.
(Yes, they did shoehorn in a few of Will's best quotations, but I could live with that).
(The lad playing young Hamnet was good).
There was a certain stillness about it that was powerful - in a full cinema, nobody moved or uttered a word for 2 hours which, these days, is impressive. I don't know how anyone could find it boring.
