What could go wrong? It’s an ad idea that is tried and true, what’s the worst that could happen?
In adland the worst that could happen is that you can predict what’s coming.
In the worst case, the scenario is obvious, predictable or trite which makes the ad a flop and promptly consignes it to vague memory.
This public service ad from Norway definitely got it right. I’ve watched it several times and keep seeing something new… or maybe I just like the points towards the end. Either way, it makes you appreciate a quick and uncomplicated journey to work.
