Season 1 was extremely captivating & enjoyable, with great characters & very interesting stories. Seasons 2 & 3 not so much, the storylines went a bit off the rails for me, and while I still found a lot to enjoy, I also found a lot of it silly & ridiculous and just plain annoying. And speaking of annoying, the sound quality is horrible! I've worn out my right thumb & the volume buttons on my remote, irritated my carpel tunnel, and hubby complains about the noise constantly! The dialogue is extremely low, especially all the whispering, and so many of the other sounds are excruciatingly loud! Between the trains, all the screaming, and most of all the 4 daughters, who in rare calm moments are delightful, but unfortunately most of their scenes seem to involve all 4 of them shrilly shrieking & yelling all at once at ear-piercing volume & migraine-inducing tones that actually make one of my dogs whine frequently. I will watch season 4 but I would really like to see more of the team working on cases and a lot less of the Leland/Sheryl storyline. But please level out the audio & rein in the daughters
