My problem is that I rarely like aquatic notes. I try not to dismiss a genre as a whole, but that "aquatic" note is very distinctive - I believe it's created mostly with calone, right? - and puts me off a fragrance.
Oddly, purely aquatic fragrances I don't mind at all - Laura Tonatto's Oltre I like a good deal, even though I don't find it very wearable.
It's kind of like my reaction to mint. Its presence totally spoils many fragrances I might otherwise like, even though the smell of mint on its own I like.
