Yes.
It won’t spoon feed you the story. you have to think about it.
It’s three stories, interleaved. Thing is...
Story One is a week long.
Story Two is a day long.
Story three is an hour long.
They all begin to be told from the start. So some events are seen two, even three times from different perspectives.
They all come together to end at the end, though one ends in Belgium and the other two in England.
If you’re willing to think about it, and keep it straight in your head, you’ll be OK.
Not Belgium, France.
