I think that's a bit harsh on Eurovision... the Italian act that won also won San Remo, the song has taken off on Spotify charts etc and on stage they know how to rock a crowd.
The Swiss, French songs could have been contenders from any year of Eurovision.
The Ukraine song was a bit out there, Iceland were a bit quirky and geeky ala Beck but that's better than all acts being generic Europop.
Lithuania went for a infectious disco song with a matching dance routine.
Finland were a bit Rage Against the Machine.
Of course there are generic Beyonce knockoffs, OTT staging and costuming (Norway), underdressed performers etc but it's far from a freak show.
You need to stand out from the crowd, but if you want to win it you need more than that.
I think there was a period in the early noughties when it was just decided on phone votes and things got a bit ridiculous.
But with the jury vote back in now it's a different contest.
Lesley Roy didn't qualify cos she wasn't freakish enough but because she wrote a song which sounded ok on radio but she wasn't able to perform it live and the staging took away from the song and her focus on singing. Similar story with the UK doing poorly.
It might suit someone like Sinead who has a profile, is in need of a comeback but she'd need a good song to do well and not sure how well her voice has aged.
