Love this series. Suchet definitely has forged his own larger-than-life adaptation of the Belgian sleuth. The productions are faithful to the time period in scenery, wardrobe, and etiquette. I hope they continue to make more episodes.
My only small quibble - I have read the books, therefore I usually know whodunit. They have thrown a few curves into the endings, though.
But then, so did Dame Agatha, even rewriting a couple of them.
