Highlander 2 is an interesting one.
Like CZ and others have said, it’s a dreadful film. I was a huge fan of the first one at the time and was crushed when I saw the sequel. The problem right off the bat is that Highlander ends; it doesn’t lend itself to a sequel at all. I always wondered how they were going to make a follow-up and the answer turned out to be “really quite badly.” Between Highlander 2, AlienCubed and Escape From LA, I’ve learned the hard way not to get too excited about forthcoming sequels to beloved movies.
HL2 was a film with huge production issues. The main problem was, the movie company wouldn’t leave them alone and kept interfering and changing stuff, eventually pulling the plug on it entirely before it was finished and then hacking together a movie with unfilmed scenes missing. It had massive continuity issues and didn’t make a jot of sense.
Christopher Lambert reportedly tried to quit during filming but they wouldn’t let him leave, and the director was really unhappy with the entire thing (he famously walked out of the premiere screening in disgust).
Oh, and the cobblers twee ending where they all turn to stardust or whatever was a bolt-on for Europe and never part of the original release. How special do we feel?
However. When it came out on video, the director went back and tried to fix it. He got rid of a lot of continuity errors, threw out the “hey, aliens!” plot line completely and basically tried to turn it into the film he wanted to make in the first place, as best he could in post-production. It’s called the “Renegade Edition,” (I have it on NTSC VHS) and whilst it’s still not a great movie by any stretch of the imagination, it’s exponentially better than the theatrical release. (I believe he went back to it again for more tweaks when it went to DVD, though I’m less sure what was done here.)
I wouldn’t pay a lot for it, but for the curious it’s probably worth a rewatch if you can aquire a copy. It’s not the train crash you remember.
