I have been putting off reading this particular play for a very long time. I hated the movie My Fair Lady with Audrey Hepburn and Doctor Doolittle in it (sorry... I can't recall his name at this particular moment). I hated how Liza just caved in at the end, cowed herself and came back to the professor...ugh!
I haven't read any other pieces by Bernard Shaw but I have always wanted to simply because I had read somewhere that as well as being a great humanitarian, he was also a vegetarian.
Take it from me, don't judge this play by movie standards, get a copy from somewhere and enjoy it as it was meant to be enjoyed. I think you will really like it. I did.
