This is not a murder you are supposed to solve because the whole set up is wrong. There is no way you can solve a murder when you are fed wrong information from the beginning. Like trying to solve the origin of a certain Wuhan-virus with false information.

Actually the movie might be about a virus. It shows a rich Moron who is ready to experiment with a product that might be unsafe and kill millions. Anyone heard a story like that lately?

We only find out about the actual murder we're supposed to investigate full one hour and ten minutes into the film, as well as an entirely new backstory. We're actively deceived by the writer. This should not be a spoiler but facts.

Why the misdirect? Because the story itself in the purest form of incredible laziness. It relies on not one, not two, but three bad writing tropes: an identical twin, a comprehensive journal, and a moron of a murderer.

Don't be a moron and waste your valuable time on this. Unless you like Greek scenery.
