Even worse is that, instead of the PTB for the franchise standing up and saying 'You don't like it, too bad. This is what we put together, this is how it stands.' They caved to the fans and made HL:III which was a bad bad
bad rehashing of the first movie.
Speaking of continuity - I put together a list:
http://www.sffchronicles.co.uk/forum/22733-things-that-would-never-have-happened-in-endgame.html back when the movie first came out (Endgame, that is), b/c I was *so* annoyed at the lack of continuity that I wanted to scream. I think they pulled some random guy who had never seen anything related to Highlander to write the script. It was bad. Just bad.
I don't even
want to know where the idea for "The Source" came from.
And you're right - the series, S1 - S4 - very good, after that - mostly crap. And don't even get me started on "The Raven", which was another 'brilliant' move that worked out so well [/ sarcasm].
