There's usually a hate-like to the contest in many places, or at least here in spain, thinking everything is only politics, and dated songs.
But when people see the contest with real eyes, and not with those only viewing the worst of it, you can actually see a huge variety of styles, and to know about many singers you wouldn't know elsewhere. it's impossible to dislike eurovision, if someone says it, he must dislike music in general, there will be songs you will like, either you're a punk or a clasical music lover.
