This is a lovely play. The characters are very much larger than life, many of the scenes are seriously funny too. Yet, there is that profound point about opportuntiy and finding one's place in this world. Shaw, as ever, takes on the role of social commentator with a moral stance.
My favourite scene is the one where Eliza objects to going in the bath: it would be indecent; a woman she knows went in every day, and she died. Fabulous!
I wondered whether having seen the excellent 'My Fair Lady' as a play would have spoilt reading it, but not so.
In fact, I preferred 'Pygmalion' in some ways. It is very similar, but the end is so much more fitting to the characters. Higgins is a confirmed bachelor and will stay such, the whole play confirms this. Why should he change? Indeed, his opinion is fixed, "Women upset everything. When you let them into your life, you find that the woman is driving at one thing and you're driving at another". He wouldn't have ensured Eliza the happiness she perceives will result from being treated like a lady rather than a flowergirl. Yes, she has the occasional flurry of fantasy about getting him on a desert island, but in reality, she wants Freddy...
Shaw's omission of apostrophes in certain words took some getting used to, but after some time seemed barely noticeable anymore.
The use of language to categorise people socially really worked and has stood the test of time. The accents are still recognisable if one is conversant with English accents and what they represent in terms of social structure. Whether this would have the same effect for an outside audience/reader I don't know. Some of the comedy could possibly be lost.
