Let's start with a quote that perfectly sums up the coherence of the plot: "Ok, let me just see if I can get this straight. You were mortal there, but you're immortal here until you kill all the guys from there who have come here and then you're mortal here. Unless you go back there or some more guys from there come here, in which case you become immortal here again."
When this film came out, it was awesome to me. I was eleven back then and it bought me with a dark atmosphere, strong cast, very good effects for its time, fast pace, entertaining action, and sexy Virginia Madsen. Now, I still liked all of that, and in addition, I enjoyed several examples of great camera and directing, as well as the very good soundtrack, but this time all of that was not enough to cover for one of the worst screenplays in the history of cinema.
"Highlander II: The Quickening" retains the actors and characters from the first film, while completely ignoring the original story. Not only that it is neither sequel nor a prequel, but the stories of these two films are mutually so contradictory that it is impossible to fit them in any way. Even if we completely ignore the previous film, this one is for itself full of holes and illogicality, and it is incredibly stupid. When it comes to story, in this movie every spot is a weak spot. Immortal's mythology doesn't work, quasi-science also doesn't work, and even romance, which is completely redundant, also doesn't work. I mean, they meet for the very first time and minutes after initial introduction they are attacked. He hides her into a garbage can, fights the attackers and kills them. Then she leaves the container and has sex with him against the wall in the middle of the street. Yea, right, very believable. How much this scenario stinks is best illustrated by Michael Ironside statement:
"Yeah, listen, I hated that script. We all did. Me, Sean, Chris... we all were in it for the money on this one. I mean, it read as if it had been written by a thirteen-year-old boy. But I'd never played a barbarian swordsman before, and this was my first big evil mastermind type. I figured if I was going to do this stupid movie, I might as well have fun, and go as far over the top as I possibly could. All that eye-rolling and foaming at the mouth was me deciding that if I was going to be in a piece of crap, like that movie, I was going to be the most memorable thing in it. And I think I succeeded."
For the nine days of work, Sean Connery received three and a half million dollars and donated the whole amount to charity. I suppose he was just trying to wash away the shame. However, apart from the story, everything else in this movie I liked pretty much, so I can not completely bury it with the rating. Audio-visually I would give it a strong seven, and maybe three for the story.
