It had some great characters, that's for sure.
Janeway, though she was inconsistently handled at times, brought warmth, toughness, and panache to the role. Balancing femininity with strength can be tough, but she had it right from the start, indicated in her preferred title ("'ma'am' is acceptable in a crunch, but I prefer 'Captain'.")
Chakotay was very likable, though I think the writers were too hesitant at times at having him oppose Janeway. They didn't want her to appear weak.
Paris was one of the best characters in the show, from his genius piloting and design skills, to his brilliant holodeck work, and let's not forget his slightly cheeky way of saying "yes, ma'am" to Janeway.
Even though Tim Russ was capable of playing comic parts, he knew that Tuvok's function was to be grounded in logic. Only in the subtlest of ways did he show that he really did have feelings.
Neelix might have annoyed people at times, but he was the perfect anti-Tuvok. Emotional, enthusiastic, and dedicated to keeping morale up in a bad situation.
Seven was at her best when she was at her iciest. People might have tuned in for her "nothing to the imagination" outfits, but she was a strong character and a fine addition to the cast.
Harry... sigh... I guess with DS9 featuring three different "young puppy undergoes major development" arcs, they couldn't give Harry anything new to do. He wound up as the "hapless guy who can't get a date or a promotion" type. Not much else is known about him. He played the clarinet. And he was Tom's pal.
And one of my favorite characters was Naomi Wildman. Just as Jake was a well used adolescent character (as opposed to Wesley the Wonder-kid), Naomi was a well used kid character. She didn't go around beating up Kazon or saving the ship twice a week, she was just a child on a long voyage, dealing with normal growing pains.
