I think there was a better play struggling to come out that didn’t quite make it...but it was a noble attempt. As a signed up member of the Labour Party and firmly believing in “for the many not the few” I too struggle with the dilemma of, do I stick to principles and not hand down acquired wealth to my children, or, do I ditch principles as they will never be able to afford their own houses without help? If I give them money (that I have more or less acquired because property prices have gone up, rather than working for it) am I just perpetuating the problem? If I don’t will they have a harder life than I did? Does that matter? I think the play would have been more biting if they had decided the youngest son needed the money more than the other two....that would have set the cat amongst the pigeons. Mind you, why I think I could possibly do better than an accomplished professional writer of plays is beyond me! Made myself chuckle....
Late arrival to the beauty that is theatre, always early to the actual show!
I think you can argue it's a pretty niche work, with perhaps only people of a certain vintage and political bent grasping some of the subtler themes.
A word that, iirc correctly, was only used once in the play has also not been mentioned here: Brexit.
If you wanted to turn it into a full 3 act, accusatory, blood-on-the-carpet generational melo/drama, there was scope - the foundation was there for a setting that explored/exposed the bitter factionalism in the current Labour Party.
It seemed to me the writer had a clear purpose, he achieved that and so we ended up with his love letter to mum.
