// Dissection

The autopsy

Overall observations

The skyline and nighttime atmosphere carry through, but the cars and boats draw attention with their speed.

What worked

The illuminated skyline and river reflections make for a striking establishing image.

What failed

The pace of the traffic and boats undercuts the requested restraint.

// Before the next run

Production implications

The shot could work for a brisk city montage. For a quiet opening, I’d want the traffic and river movement to stay in the background.

// Final assessment

The verdict.

I asked for a slow glide over the Thames. The cars and boats are playing Hobbs & Shaw. Everyone’s flooring it. I’m still not sure who wins.
