getawaywithit has edited the TV wiki that I mentioned a few days ago, to add an entry about Blakes 7 relating it to various TV themes identified elsewhere on the site. In the spirit of the wiki you may wish to extend this, or add your own favourite shows.Linking from this, I like the definition of the five-man-band, as seen on Scooby Doo, Mission Impossible, Star Wars etc.
The Hero - the clean-cut, upstanding youth. Luke Skywalker, King Arthur or Robin Hood. Captain Kirk, Captain Picard. Generally The Captain. Aragorn. Buffy. Lead singer. John Crichton. (=Blake, Tarrant wannabe)
The Lancer - the rough-cut, grizzled warrior anti-hero. Han Solo, Will Scarlet, Launcelot. Will Riker or any other Number Two. If someone is going to go Shape Shifter it will often be this guy. Boromir. Faith. Lead guitarist. Aeryn Sun. (=Avon)
The Big Guy - the strongman of the team, often dumb or mute. Chewbacca, Little John. Worf. Gimli. Xander, sort of. Bassist or Drummer. D'Argo. (=Gan)
