As war movies go, there isn't all that much fighting and almost no blood, but you'd need a chainsaw to cut the tension. It's perfection on many levels, if that's the style you're looking for.
Incredibly well done by Christopher Nolan, but he has no idea how movies are going to live in the future. Those who have a great visual will continue to draw people to the cinema, but the rest will be streamed.
As a side note, IMAX or 70mm formats are probably worth the investment.
Mark Rylance and Tom Hardy.
