I really don't know what I think of this ad. The first time I saw it I was pretty confused when the brand came up, but after more consideration it starts to make a bit of sense.
For me the execution says more than the line does, the idea of breaking through boredom and gloom says far more about the station than the endline. You could take the line away and the ad says just as much, if not more by removing the need to think about the link instead of just absorbing the wonderful mood it makes.
Shame the unecessary line tarnishes something that otherwise is great.
