As a whole the both seasons were pretty good. Great idea. But was not great.
So many things don't make sense or are just weak writing and scenery. Lupin, the most wanted man in France, just walking the streets freely, while on every front page of the paper. Weak. Also the last episode where he tricks the guy into thinking the safety is on, is laughable.
And then magically his Mrs decides to come and meet him at a bridge, having no idea he somewhat cleared his name, after only just recently, banning his son from seeing him.
Don't know what you 4 and 5 star people were watching tbh.
