Highlander the Raven was a bad show but I wouldn't blame the character of Amanda for it. First the name was bad because A) there was no Highlander in it) and b) since when was she known as The Raven? then yes Amanda was a character of questionable morals who wasn't as powerful a fighter as most of the imortals but she's survived. The question is "Why?" and the answer is not that she ran to Duncan for help. finding out how she survived all these years on her own would have made a good show. The problem was the lame hook her up with a mortal cop story line. That was what made the show bad. Notice the same thing is killing Birds of Prey right now ironically a female driven show with a woman who reminds us of Catwoman in the lead role. Anyone ever notice that Buffy is a hit show and she doesn't need to run to a big strong man to defeat her enemies.
