To you, does "The Search for Vengeance" exist within the expanded universe that includes the TV series and most of the other films? Was Duncan and/or Methos somewhere out there during the events of the movie? Was it just its own thing to you?
I've always thought it strange that if Highlander were to venture into the realm of animation they wouldn't want to involve Christopher Lambert, Adrian Paul, and make it this big thing in animation that they couldn't do in live-action. Barring that, though, I guess in the back of my head I was hoping that The Search for Vengeance would do at least good enough to warrant a sequel... and Colin would encounter/team up with/fight at least some Immortal characters from the other stuff.
