Highlander, for me, was nearly as significant as seeing Star Wars (A New Hope) the first time. I think it's because I was a teenager when I saw Highlander and it really spoke to quite a bit of how a teenager views the world and what I found cool at the time (trenchcoats and katanas).
I found the development of Connor through flashback very interesting, but didn't remember the segments set in "modern" New York as being as disjointed and grim as they were. I'd also forgotten that those same modern set pieces reminded me of a music video (probably a good thing back then).
And Christopher Lamber was an...odd choice for leading man. I felt that Sean Connery and Clancy Brown both did a much better job and in many ways felt that Roxanne Hart's Brenda Wyatt was a more compelling character than the 1980's Connor McCloud.
I find that truly sad.
