The actual petals and other important parts of Masdevallias are stuck way down in the center of the plant, and are tiny. The sepals, which have become fused together, are the brightly-colored bits with the long "tails."
I think most of the Masdevallias I've seen are less pretty than just odd. I like odd, usually, so that's not really a problem. And the first one I posted about, Masdevallia Prince Charming, I actually think is kind of pretty, too. Everything breaks down with M. ignea x constricta, though, as my brain insists that it's creepy and off-putting. The odd shape, combined with the large numbers of flowers in these pictures, somehow add up to "alien invasion" in my head.
Also the color, let's face it, is not the most appealing.
Maybe if they were edible, and tasted like cheese, it would work for me.
Though I'm not a big fan of cheese either, actually, so maybe not. I don't know.
Masdevallia is another genus I will probably never grow, though I have more hope for Masdevallia than for Miltoniopsis; Masdevallia might be okay in our basement. It's humid and cool, and there are fluorescent lights all over the place, so if I managed to water often enough, I might be able to keep a Masdevallia happy. Not, like, an alien cheese invader Masdevallia, but with some other, more pleasingly-colored hybrid.
