I've watched the first two episodes and what struck me (and it seemed, the advisor of the Queen) was how desperate M A-F was to be part of the establishment. He loved all of that and wanted a British passport and wanted to mix with the higher orders. I don't believe Mo paid the paparazzo but he certainly engineered the relationship and after they died he already convinced himself the relationship was on a sure-footing because he still wanted to be part of that society. Did his son dying in the same car as Diana kill his ambitions? Most probably.
The actor who plays Mohammed is outstanding.
The actor who played Dodi was too. Browbeaten, harassed, never good enough. His fianceé wasn't the right type to get her father in law the British citizenship he desperately wanted. Hence why he wanted Dodi to pursue Diana, who was born an aristocrat.
Debicki has Diana's movements down to a tee. Not just her face, but the way she walks, gestures, everything. It's so good. But I find myself drawn to the Fayeds more, and I don't give a stuff about the RF.
