Uhura, Sulu, and later on, Checkov, faded into the background. Great episodes like A Taste of Armageddon, but also a lot of duds. This is also the only series in which the Romulans are actually competent antagonists, rather than being mustache twirling evil buffoons as in every other depiction. Wrath of Khan and Voyage Home are the only good Star Trek films.
The Next Generation: the first two seasons have a few good episodes (like Conspiracy), but overall is mediocre. There is a lot of preaching and sermonizing here. Starts to get good in season 3. I did like Dr. Pulaski from season 2, kinda miss her. Best characters were Picard, Data, and Worf. Riker was fine. Geordi was kinda wasted. I really liked Wesley after he left the Enterprise, loved The First Duty. Miles O'Brian and Barclay are also great when they appear. Troi is bad and Dr. Crusher are forgettable.
Deep Space Nine: by this point, the franchise has had two shows about traversing the stars in a Federation starship. Rather than rehashing the formula a third time, DS9 does something really different and begins to use the universe that has been built up over those two shows to tell a serialized storyline. DS9 starts off as just another episodic Star Trek show, but by season 5 it's pretty much evolved into a serialized drama about a conflict between the Federation, their allies, and the Dominion (an evil counterpart to the Federation). Where DS9 suffers is in attracting new people to Star Trek. TOS and TNG were variety shows, where anyone could tune into almost any episode and be treated to something new, and get a self contained story within 40 minutes. DS9's early episodes are a little like that, but by season 5 the show is firmly a serialized drama where the storylines of the episodes rely on knowledge of the setting, the characters, and the plot as established in prior episodes. A person who has never watched Star Trek before who tunes into "The Siege of AR-558" isn't going to know why these two forces are fighting, what the stakes are, why they should care about these characters, or anything. The other problem with DS9 is that it is where Star Trek begins to be infected with a post-modernist slant, with the Federation being depicted as just the United States but in space, instead of the idealic utopia presented in TOS and TNG.
