One of the most boring movies of all time

Rating: 4/10 (18 November 2017)

I have seen only some clips of this movie earlier, but just now I watched this entirely and I am sad that I did. Just lost two and a half hours of my life that I'll never get back.
First, this is a movie, who wants an overture in movies? Then, when the movie "starts" is like 20 minutes monkeys just jumping around and doing pretty much nothing.
Then there is intermission, maybe it's part of the old-fashion movies, but leave it to those who are AT THE movies, not the ones who just want to see the film.
Yes, there were some good parts, but mostly it is just silence or very irritating buzzing sounds.
I can't deny that it was not ahead of it's time in 60's, but I am watching this now, almost 50 years after the making of the movie and the rating will be this.
My rating will be based on pretty much of those little clips I've seen of this film before the entire movie, some brilliant techniques were used to make this film.
