I started out hating the Ferengi and Quark especially. Over time all of these episodes won me over, even the bad ones. I can even find things to enjoy about 'Profit and Lace' which kind of plays out like Three's Company on a space station or something similarly ridiculous.
I did think that they pushed some of them too far into the comedy realm. I don't have a problem with Quark and company being played for laughs, but there were certain episodes and situations where the humor takes over way too much. They should have let the laughs come more naturally and not forced them into every other line screaming "hey do you get that this episode is WACKY!!!!!"
