Currently watching Poirot (the series) for the first time. Hard to believe it started in the 80’s - the film quality is so high, it looks great even on a large TV today.

And the production values overall are amazing. The cars, the clothes, the buildings, etc - they really captured the 1930’s. I really appreciate the clear, well-balanced colors, too, none of today’s high-contrast, over-saturated crap.
