I don't really have a high opinion of marketing, I tend to look at videos like that and go "what a load of codswallop"
I guess that it's good the design is good enough to gloss over that

Really don't know why some people have been critical, I still think it looks brilliant - it makes a great livery for the Metro and the coach too. The colours are lovely and very 'neutral' - they don't make you think of any Eurovision country. I guess they could have been blue and yellow for the colours of Ukraine, that would have given a lighter feel to the design, but obviously Ukraine didn't feel shameless self-promotion was in-keeping with the "Celebrate Diversity" theme
Unlike the Swedish dandelion logo which really had nothing to do with the theme "Come Together", the different sizes/patterns/designs in the Ukrainian logo, as well as the blue/pink colours, are definitely inkeeping with a "Celebrate Diversity" theme.
