She's the one who can detect emotions by having orgasms? Her ensembles are certainly notable even 3 episodes in!
They make a bit of an effort to push them as the big recurring villains in the earlier seasons, then they end up as a bit of a joke for the most part and you get better baddies as well as returns for Klingons, Romulans etc later on. DS9 has some Ferengi regulars that it actually develops into interesting (but mostly comedic) characters, but that's a while off.The Ferengi are rather tedious and unbelievable. I had my phone engaged almost the entire episode.
