First off I'd have to say I think series 11 is possibly one of the weaker of the Poirot series. I didn't really love the three that came before this one, and I remember not particularly liking this, but on second viewing, once again I loved it. The music is gorgeous throughout, really good, it's a visual treat too, the scenery is stunning, the big scale big budget feel works so well here, has a more grown up feel then say Murder in Mesopotamia.
Cheryl Campbell gives a great performance as the nasty sadistic Lady Boynton, an actress that is often sweet in her parts, is particularly nasty. The story is not one of Christie's best, and I feel that some of the changes they made greatly benefited the story, an average novel is made into a very good drama.
I wasn't overly fussed on Tim Curry in this, I found him a little bit over the top, I had a huge difficulty believing in any kind of relationship being possible between Campbell and Curry's characters. Mark Gatiss had some very humorous lines, I'm sure some feel Poirot has no place for humour, but I appreciated it. As a lifelong fan of Angela Pleasance I was surprised how good she was in the part, I don't think she even spoke? It's heaps better then the Ustinov film, which has always felt like a cheap low budget b movie.
It's way better then the reviews here would have you believe. 8/10
