Even though the sets are decidedly constructed, the dialogue is sometimes questionable ("How on Earth could you possibly know that," Dr. Israel asks Rijkers about a strange knot found on a crime scene, to which he responds, "I'm curious about detective work everywhere"), and some of the performers are limited, the fact that every single thread is on track to tie neatly together (at least from the vantage point of episode 5) makes the show supremely enjoyable. And it has so much heart, you can't help but buy in.
