There is a lot of dumb stuff, but also a bit very cool space pew pew, very charismatic actors and occasionally Odo emerging from a wall panel, being one step ahead of everyone.
Also, the versatile actors playing different characters are awesome, if you know about it. Oh and the mirror universe.
I love all the day players that are the villain/vicitms of the week. It's kind of hilarious to see the same actors again and again, but also a lot of them were also on Babylon 5.
The characters are mid and despite there being six seasons there are only four episodes:
Odo solves a problem by changing shape
Propaganda for the Bayjor religion
A beloved crossover character saves the day
Something unimaginably horrific happens to the O'Briens
