I agree season 3 is a terrible season. They were clearly out of ideas, that's why they needed a gimmick character so badly, so they wouldn't need to come up with good ideas.
Let's see, episodes...
Flashback, False Profits, The Q and the Grey, Alter Ego, Coda, Blood Fever, Darkling, Favorite Son, Distant Origin
The Swarm, Remember, Sacred Ground, Warlord, Macrocosm, Fair Trade, Unity, Rise, Real Life, Displaced
Episodes I might actually be interested in seeing again:
Basics, The Chute, Future's End, Before and After, Worst Case Scenario, Scorpion
Very, very weak season. Maybe the worst 24th century season.
