Maybe this one would actuallbe a good choice for a reboot or remake...?
No.
Not because it couldn't be improved upon, it can. Oh boy it can.
But for some unexplained reason, every single time they try to make new Highlander material it gets worse and worse. The Quickening was terrible. The Series' were mediocre at best, and soap-operatic trash at worst. The cartoon made NO friggin' sense. The Final Dimension was completely stupid in the way only 90's action films can be. Endgame, while not bad, totally messed with the mythos of the franchise. And then there's 'The Source', which I regard as the absolute
worst piece of cinema ever created. Seriously, I've seen porn that would stand a better chance of critical acclaim.
Not to mention, that Lambert, Connery, and Brown wouldn't be in it. I cannot see anyone but Lambert as McLeod. Connery and Brown were just too good to be replaced.
Basically, I say leave it be. It's a schmaltzy Sci-Fi Fantasy romp that is perfect in it's imperfection. To remake it will only serve to diminish the Cult Classic status of the original and/or further damage the franchise.
