The Buckingham Murders

Review time. I recently watched this movie with no expectations but it pleasantly surprised me. Why it's not popular and nobody talked about. It's a great one time thriller flick. The plot is good, the performances are impressive and the climax really takes you off of your couch. After Kareena's Jaane Jaan I wanted to watch a similar toned movie. And if you have liked Jane Jaan you'll also love The Buckingham Murders. One thing that I wonder that if this movie was made with with the similar story based in India it could have achieved more success as Language might have been a limiting factor as around 40% of the dialogues are in English.
