Unlike the previous commentator who failed to understand the historical importance of this piece of film and tried to review it in the context of 21st century technology, I would give this 10 out of 10 for the fact that without Le Prince's pioneering work, cinema as we know it might still be a pipe dream.
In terms of 19th century technology, which is the context in which it should be reviewed, this film is cutting edge.
The subject is recognisably a road across a city centre bridge in Victorian times. We have all seen plenty of still photographs from that era but in this composition, the horses and people actually move. I come from Yorkshire and I know that one branch of my family was resident in Leeds at this time so, who knows, one of those people could be a long-lost ancestor of mine. That's a romantic view but you really can't take anything other than a romantic view of something like this.
To see the film, follow the IMDb video clip and enjoy a glimpse of a bygone age. The title mentions traffic but you won't see any horseless carriages!
Absolutely fascinating.
