I think the Capture is hilariously awful. Really really bad, but quite entertainingly so.
Some of my very favourite programmes ever are on BBC - The Repair Shop and Saving Lives at Sea. If you don't know them, The Repair Shop is craft experts repairing old things (clocks, furniture, dolls, boxes, stuff in general) for people, and I love it because they're so skilled, and it's just a lovely, charming, sweet programme.
Saving Lives at Sea follows various RNLI stations and shows footage of various rescues at sea or on the Thames. Very exciting and dramatic, and the RNLI staff are absolutely amazing - so brave and caring.
I also love the Scandi/Euro crime drama slot on Saturday nights. Spiral series 6 is currently being repeated in advance of Series 7 coming up.
I also really like many of the BBC 4 documentaries.
