In reply to deepsoup:
I've taken the liberty to assume I might be wrong on this so have just finished watching it again! Perhaps I was harsh regarding the reading, some of which did work. I do moss some of my favourite lines ("downs his last bucket of black brackish tea and rumbles out bandy to the clucking back where the hens twitch and grieve for their tea-soaked sops"). But I still don't like it.
Let me explain. The effect UM had on me when I first listened was to take me back the the culture of the small town I grew up in. A claustrophobic town with agoraphobic inhabitants. People from every spectrum stuck, forced together, making do as best they can. Hopelessness (Polly G., No-Good-Boyo, etc) abounds interspersed with hopeless hope (Gossamer Beynon and Sinbad; Myfanwy and Mog) and despair (Mr and Mrs Pugh). Sadness is covered with aggression (Mrs Ogmore-Pritchard) or humour (Mr Beynon). The town is coloured with character yet bleak.
So what happens when the characters are dispersed? Captain Cat overlooking London, healthy, tanned and smiling evokes no pathos. Perhaps the visual 'success' is a metaphor for life experience. An American bar has little to do with the play or Welsh culture. The smiling, beautiful people reading the words don't carry the sadness, the darkness and pathos of those stuck in a grim, isolated seaside village. All I could see was a sea of cameos.
Dylan Thomas, for me, was a welder of words. Beautiful structures made form disparate parts. The radio version has survived so well because you want to concentrate to enjoy every nook and cranny of the text. Music in the BBC radio version was just enough to direct emotions and convey the scene, always sad. Rollicking pub songs don't work. Polly G.'s song conveyed the 'diamond in the rough', really standing out from everyone else in the play. Bryn Terfel rather ruins this: while K. Jenkins sings beautifully she is light years from Mr Terfel in quality.
So I fell I have just watched Strictly Come Acting: Wales. Entertaining perhaps, but ultimately vacuous.
