After reading all comments (which tend to be slightly negative) and knowing Spain's ambition to end up bottom 5 every year, I prepared myself for the most generic entry possible.
That said, I'm surprised! - Personally, I think it's one of the best Spanish entries ever! - I'm not even kidding... It will definitely be not among my favourite entries and I can't see it inside the Top 10 in May but honestly, it's a well-crafted and brilliantly produced pop song: It's catchy and memorable and Blas Cantó's tone suits the song. The choir in the background sounds good to me as well.
It lacks some oomph, though, to be really impressive but there's no way it will be bottom 5 when there are juries involved.
I give it 8 points because on paper, it's a good entry and it's my favourite entry from Spain since 2012 but I'm not amazed or blown away.
