I like it. It's witty, well acted and directed.
This version of Lupin is a clever re-imagining (with some flaws), trying to fast-forward the original character 100-years. And yes, XXIst century Lupin is the son of African immigrants. And why not?
Omar Sy is a great lead character and the production values are good. Perfectly enjoyable light entertainment. I repeat: this is meant to be watched for fun, it's not faithful to the details of the original books, it's not meant to be realistic. Good tv is escapism.
It reminds me in a good way of successful series like Hustle, or Leverage. with intricate cons and twists.
To the critics: you are right, this is not a series of Lupin faithful to the original books and historical context, in a way that David Suchet's Poirot was. But it is in the same line of re-imagining classics (though not quite as spectacular, but neither on the same budget) as Dominic Cumberbatch's Sherlock.
It's an enjoyable ride. Don't begrudge the artistic licence. Have some fun. For god's sake it's 2021!
