This is easily the best of all the Star Trek series. The characters are likable, and develop well over time. Of course it helps that many of the characters are warm and funny and very well fleshed out. Quark is a favourite of mine, always funny and well acted. The story itself is great, and really picks up in season 4. Having a plot that develops throughout rather than just stand-alone stories like many of the Next Generation episodes helps it a lot. The Religion v Science aspects are an interesting addition to a science-fiction show. Ideas created in TNG are carried forward and developed, such as the Trills, while in TNG they simply move their personality to a new body in this the idea is taken further and the personalities are merged, making the race much more interesting. One of the great aspects of the show is the relationships between the characters. O'Brian and Julian seem like genuine friends, Odo and Quark and their rivalry, and the on going feud of Sisko and Gul Dukat, the two commanders of the Station. The series created some genuinely good characters. Sisko, the Federation Officer torn between duty and destiny. Garak, the traitor with decidedly dark past, and Gul Dukat, a truly great villain. The series succeeds with a grand plot, paints a wider picture of the Star Trek Universe, and would make for some great feature films.
