The Ferengi were an inspired addition to the franchise. With the end of the Cold War the Federation/Klingon tension felt out of date. The series needed a new foil for the touchy-feely Federation.
The Last Outpost had NO Wesley in it, making it one of the better S1 episodes. Also, Data getting caught in a Chinese finger trap is classic.
And then we're back to Wesley episodes, the kid gets a field promotion to "acting Ensign", which makes not a lick of sense. My theory about these is that the producers wanted to attract younger viewers to the series, so they made Wesley prominent.
Worf's pet boar was adorable, though. The wild boar Emmy-Lou would... well, let's just say she left her own special mark on the show.
