I get what you're saying. I loved "The Highlander" when I saw it as a kid, and I thought the mystery of why they became immortal was perfect. When they made the sequel, I hated it so much that I just purposely blocked it from my memory and just imagined the ty sequels never happened.
I am not a fan of the original King Kong (I have never seen the complete 1933 movie, or the 1970s version either. I've been meaning to)
I did watch the 2000s Peter Jackson version, and thought it was fine (loved how they shot the 1930s period, hated the overly flashy and rushed pace of the action and their overuse of CGI) I know how the movie was supposed to end, and I did not like it. Too much of a downer for me.
This new one made Kong into a bigger dude, stronger, meaner with a heart for other living creatures, and they did not portray him as a tragic character that's destined to die in the end.
I think they adjusted the story a bit to appeal to younger people who are just getting introduced to King Kong.
He's a hero in this movie. Bloodied but victorious. Wild and free. King of his world.
Much more fun to re-watch in theatres again, with friends. Popcorn action flick. I'm planning to see it again next week.
The old story of King Kong is too much of a downer to re-watch often.
