This isn't really a programme about Coastal Railways. It's a programme about Julie Walters.
This isn't necessarily a pop at Julie, who seems lovely, but every time you want to see the railway journey, you have to swerve to look around Julie.
In this she follows a long, long, line of celebrity-obsessed television productions. As if the world somehow revolved around the 0.1% of that demographic and as if they are the arbiters of anything and everything that's interesting about places.
These railways are fantastic. It would be even better if the 'me, me, me' brigade just stepped aside for a bit and allowed the rest of us to see them, in all its glory. Without someone's fizzog in the way.
For an example of how to do it, see the brilliant Channel 5 series 'World's Most Scenic Railway Journeys'. The clue to their success? Bill Nighy the narrator never once appears on our screens. Bravo.
