I watched Bodyguard weekly in 2018 when it originally aired and I've rewatched it a couple times since then and I love it more and more each time. It really does maintain its suspense and intensity no matter how many times you watch it. The writing is phenomenal of course by Jed Mercurio who wrote the incredible Line of Duty (2012). Where it was written by Mercurio everyone expected a high calibre crime thriller and that's exactly what we got. The acting is amazing, especially the main characters played by Keeley Hawes and Richard Madden. I'd love to see second series at some point in the near future.
