To me it seems strange that the explosion doesn't really affect anything. Nothing flies off the door and the soldier runs right through it. So it looks more like a harmless flash or light phenomenon rather than an explosion.
In my view there should be a lot of debris in the air, plus dark smoke, in addition to the flash. And I expected the soldier to fly off to the opposite wall, not run right through like nothing much happened.
The way he "fades in" through the explosion looks very unnatural.
