Absolutely ridiculous attempt at story telling.
I understand time passes but all the things that happen just seem ludicrous and the ending is beyond the pale.
Here's my shallow superficiality - did they purposely cast the least attractive English actors they could find for each and every role? Was that a conscious choice? I mean, you can fall in love with someone who is not societially attractive but every single person? Aisling was the only saving grace - pretty, funny, smart...Of course, she was Irish. (I know Jack was but ... c'mon!)
OK - back to the review - I think we can all see how ridiculous it was that they got intimate in the injection room only to find out that she has cancer only to find out that he has a life-threatening syndrome only to get in a car accident and on and on.
Utter nonsense that Alice can suggest to Celia that she take ballet and, with that very late start as a ballerina (most start at 4 years old or so), she excels and gets a solo show at some swanky venue. Uh huh. That is realistic.
No one ever ages over 15 years, not with all the pale Irish and English skin exposed to the sun. No matter what their unhealthy lives expose them to. They look exactly the same.
The bottom of her hair is bleached - early on, it's evident that she's growing it out and that's from a previous dye job. But 15 years later and all the years in between, it's always bleached in the same end spots. Plus she never changes her hair in 15 years?
She is SO incredibly unpleasant. From the get go. She is so negative to him and so unhinged and awful. Then we get the tired trope of why - how unoriginal.
When her father dies at her mother's burial (this seems to be a theme - dying in reaction to someone else having died), the news media immediately shows up to this tiny burial ground in this rural area and broadcast it all over England so that, back in London, his wife sees.
Is this actual story telling or was this the final paper turned in in someone's creative writing class?
