The Ferengi episodes are sorta much more extreme when the rest of DS9 because they were all intended to be funny. And so when they were good, they were generally very, very good...and when they were bad they were horrible.
I don't always dig the intended "funniness" of the Ferengi episodes either. But even in episodes where I ain't appreciating the "funny", I can always
find something to appreciate about Shimerman's, Eisenberg's, Grodénchik's and Combs' performances. IMO their great acting almost always keeps the episodes fascinating regardless
of if the plot is semi-weak, or not as funny as intended.
