Even I, who can't stand Doyle generally, would have preferred to see that as his casting concept seems to me a better idea than the standard one seen in the revision of people in the middle of the age range.
Having said that, I didn't hate the London version as seen onscreen. I didn't love it, but I didn't hate it. And I liked the Charley a good deal. Perhaps more than anyone since Lonny Price, who still remains the standard as far as I'm concerned.
