I am only halfway through the first episode, so we'll see how it plays out.
However, I had to respond to @Pattywolford's comment that there are no "likable characters". Perhaps s/he meant that are no likable _white_ characters, I certainly find plenty of likable Indian characters: Sooni the sloganeer, Alice's childhood hair-puller (now her brother's Rolls-Royce driver), the mysterious freedom fighter with a revolver, the Indian woman on the train who dares correct the Memsahib's pronunciation of "Persephone" ...
One minor quibble: the Indians speak English with a weird accent that sounds as if it were the result of a Brit's imagining of an Indian accent. And, they seem incapable of pronouncing Indian words correctly, to wit - "zindabad" is pronounced "zindaabaad" not "zin - d - baad".
Stay tuned for more post-colonial commentary and unfavorable comparisons of all the Englishwomen to Edwina.
