The book is NOT better, haha
"The book is better"
-is one of the biggest (and most annoying) movie cliches I hear all the time, but it does NOT apply to Congo.
I'm not saying the movie was absolutely amazing or anything, but I just read the book and now I actually prefer the movie.
The book is a bit outdated, which is understandable. But that does not make up for the ongoing hoakiness the book had with communicating back and forth between Africa and the USA. They can't even afford to send too many letters (like ABC) through the satellite but they can send video and sound files?
The book would often breeze over big action scenes. Like, oh yea there was an attack on the plane so everyone jumped out. Then 3 pages on the history of Zinj...The movie of course had more action, which is expected. But the book did not really have any character development. Amazingly, I think the movie had more which is often quite the opposite.
Karen was not going after her missing husband in the book. So that whole dynamic between her boss forcing her to go for the diamonds and her only wanting to find out about her husband was not there in the book. This was not a bad element of the movie, so I think the movie scores here.
The book did not have the Tim Curry or Peter's-friend characters. These two characters added more to the movie because they gave the gorillas people to kill! LOL (plus Tim Curry was comical, which the book had none of). So since the book basically just had Peter, Karen and Munro...nobody was killed except a few African porters they hired. Some may argue that adding those 2 characters simply for gorilla fodder is a cheesy, lame attempt to copy Alien, Jaws or Jurassic Park cause animals killing humans = entertainment. Well yea, that's true.
The only point i'll give to the book was the scene with the cannibals devouring that family. That was interesting and I wonder if they considered that scene for the movie.
