well, I haven't really read any books of Agatha Christie (except The Death on the Nile) and as a viewer, I found this series so enjoyable! and my favorite Miss Marple is Geraldine McEwan because i thought she amused me kind of sad she didn't continue but it's understandable! when the plot was sometimes didn't really work on me, I thought it's something that made me want to watch it more and ended up wanting to watch more. It's one of the first British TV series that I watched, and it's something that I wouldn't regret. Ms. Marple is such an unique and authentic character, and it's kind of unfortunate she didn't as popular as Poirot.
