Basically Highlander 2 has NOTHING to do with the first Highlander. And besides that, it sucks. I can honestly say that it is one of the worst movies I have ever seen.
I wasn't real happy with it either, but there were some good parts. Some of the plot is very strange and doesn't really make sense or follow the other movies though.
The 3rd movie sort of makes sense. McCloud is the only one at the start until some dead and crushed immortals are found and brought back to life while some people are digging.
The last movie, (4th ? ), had some things that really didn't make sense to me and I don't like how they made Connor to be sort of an old man and a wimp. Why did they make him seem so old? He can't age! I don't think he looks that bad in real life.
And the ending doesn't leave us with one immortal.
And wait a minute, where did all those other immortals come from? There was only 1 after the first movie, one after the 2nd, 1 after the 3rd, but somehow there are a dozen or so immortals for the start of the 4th movie? How does that fit into the rest of the movies?
