Lots of the action may be intense.

The final fight is very brutal and intense.

The bar shootout/fight is very sudden and intense, as well as violent.

The film opens with a group of terrorists holding several innocent people hostage, and they hold a gun to one man's head. Very intense.

There are many scenes with flashing/bright lights, and there are also abrupt changes between dark and bright scenes, which could cause seizures or disorient some viewers.
