Spotted this was on Amazon Prime today and yes, it was delightful! I had read the book but FOREVER (pun intended) ago so didn’t remember much, but it was a really feel good bit of fluff, well acted and the lead was delightful. 9/10.
If never read the book but watched this on Prime over Christmas too. Really lovely and well done. The scene with Rachel McAdams telling Margaret about her parents made me sob a bit.
