Maybe those people have only experienced some of the really potent leathery & peppery, bitter and astringent green frags on people who have drenched themselves in fragrance. Good! (returns witchy smile) - more for us! Or perhaps it's that the green chypre style has been out of fashion for so long that most people don't relate to it. I adore the greenies, though not all. I can't wear Miss Balmain (extreme peppery coriander & raw hide leather), didn't care for Bandit (though may revisit to reassess), and especially hated Coriandre way back when. Greens I do love -Y, Fidji, Givenchy III, Jolie Madame, Miss Dior - are usually from a bygone era. Safari was really nice too. But I think the new Pucci Vivara is great (though I may be in the minority on this one), as a modern green, though still very green, and sweetly floral. I guess I like florals in my greenery.
Scary greens: Miss Balmain, Paloma Picasso, Bandit
Friendliest greens: Jolie Madame, Aqua Allegoria Herba Fresca, Annick Goutal's Eau de Camille, probably some of the Demeter ones are nice, though I don't know them.
