I personally loved it, but I'm a Poirot Fan. If you like a good 𝘖𝘭𝘥 𝘍𝘢𝘴𝘩𝘪𝘰𝘯𝘦𝘥 Who-dun-it, then you should find this enjoyable. It follows the basic Agatha Christie style of Mystery. I really liked the all familiar- "it must be person A" only to find out that it's "person z" (who may have crossed our minds, but we quickly dismissed) - Storyline.
It's got the old fashioned charm that most of us have come to love.
Of course, if you are a fan of crazy special effects or the graphic slasher film, then it isn't for you. To each his own, as everyone has a right to enjoy what they enjoy. That's what makes the world so interesting anyway; Therefore, if you like the old fashioned mysteries, then it is for you.
