Best scifi TV series ever, IMO.
Breathtaking moments:
Sheridan's rescue by newly unveiled Kosh after terrorist plants bomb
Sheridan going to Shadow homeworld--Melissa Gilbert, the guy that looked like Capt. Kangaroo (creepy!), atomic blast of domed city, etc.
final episode
devastating bombing of Centauri homeworld
unveiling of Sinclair/Valen (probably my favorite)
Battle of the Line
any of the incredible space battles
the different architectures of the spaceships
Lannier's betrayal--and redemption
seeing a spider vessel unearthed by archeologists
the way the Shadows are slowly unveiled over many, many episodes
death of Centauri emperor (the aged one)
Anybody else care to reminisce?
