I've always felt the ratio of Galactica episodes breaks down pretty much the same for one year as Trek did over three years. One-third good, one-third average, one-third bad. My groupings.
Good
Saga Of A Star World
Lost Planet Of The Gods
Living Legend
War Of The Gods
The Man With Nine Lives
The Hand Of God
Average (Some are slightly better than others but all are middle of the pack)
The Lost Warrior
Gun On Ice Planet Zero
The Long Patrol
Fire In Space
Murder On The Rising Star
Baltar's Escape
Below Average to Bad
The Magnificent Warriors
The Young Lords
Greetings From Earth
Experiment In Terra
Take The Celestra
I will admit even the bad episodes occasionally had a good point or two like the location filming at the ruins of Expo 67 in "Greetings From Earth".
Can you expand upon your last sentence? Ruins of Expo 67? Not familiar with that.
