Let me just say from the outset that I simply do not agree with you at all, the Godfather is a classic piece of film-making and most importantly storytelling.
I do however have to pick up on a few points you have made
THREE HOURS! They took three hours to say what could have been said in less than one.
And had they taken one hour to say it the film would have been ruined; simply turned into a series of pointless and threadbare gunfights and slayings. This comment (for me) is on par with the people who moan that 'Man on Fire' and 'The Deer Hunter' have too much talking in them and that the films should just have the action bits in them.
The acting was decent, that was about it. The script was horrible. It had no emotional development whatsoever. I felt nothing for these people. The most important thing a movie can do is tie the audience to the characters with some sort of emotion, be it hate, love, whatever. I felt nothing. No drama, no climax.
Well no one can force a reaction on you, but I strongly suspect that you may be in a rather small minority here. Its also potentially at odds with the comments above about the film being too long. A huge amount of time in The Godfather is spent building the relationships between the family, particularly the relationship between Michael (Al Pacino) and his father. The struggle he undergoes to avoid joining the family business and the realisation that he has little choice if his family is to survive.
Sorry but to condemn The Godfather for a poor script and a lack of emotional development is quite frankly amazing to me, if you would not mind could you give me an example of a film that you believe did this well?
Every scene of this movie was predictable. I saw around every corner. I am somewhat partial to the genre of mafia movies, and yes i consider mafia movies their own genre.
Not a huge surprise given that just about every gangster/mafia film since 1972 has ripped the film off to a huge degree. The Godfather is only predictable because you've seen these films the 'wrong' way around. I first saw the Godfather over 20 years ago and for me its every other gangster/mafia film that's predictable.
The only reason I'm bagging this one so much is because it's revered as one of the greatest movies, if not the greatest, of all time. I've seen a lot of movies. A LOT. And this is one of the worst, if not the worst, movie I've ever seen.
In that case I can only conclude that you've been lucky enough in life to avoid a simply huge number of very, very bad movies.
As a start I suggest you give the following a go
Battlefield Earth
Shanghai Surprise
The list could go on and on, but it is rather interesting to note that The Godfather is still the number one rated film on
IMDB.
