What makes a story great?

We all know this situation: You read a book, shrug, and forget about it two months later.
We also know this situation: You read a book. It's awesome. You can't stop thinking about it. You often reference to it in serious conversations or jokes. You read it 4-60 times and still enjoy it. You get ecstatic when you find out it's going to be a film, complain when the film has left the original book in the dust, and read the book again.
So how does this happen? What was the difference between the books?
Content themes? Perhaps.
Plot? Most likely.
Lessons? Maybe.
Style? Definitely.

One of the worst situations when writing (or reading) a book is when it's chugging along, the audience is happy, the suspense is high, and then...then...then?!...BAM! Pointless back-story dumps, obvious statements, and meaningless objects are pointed out. That is a sure-fire way to KILL a book.

There are other ways, but to explain that, I'll explain what makes a great book:
1. It has a good moral center.
(Narnia; Lord of the Rings; Monster; Les Miserables;)
2. It challenges a popular (twisted/confused) view.
(Oliver Twist; The book thief;)
3. The characters are connectable.
(The hobbit; Monster; Pride and Prejudice; The book thief;)
4. It shows true change and/or redemption.
(A Christmas carol; Les Miserables;)
5. It fulfills the basic virtues.
(Lord of the Rings; Narnia;)

1. A moral center:
There is a common understanding of what is right. If you don't believe me, read C.S. Lewis' Mere Christianity. Stories that reflect this are some of the best. Even Guardians of the Galaxy does this.
 The hero, at least, should recognize and act on these. A good example is the scene in The Hobbit when Bilbo, who has been threatened and betrayed by the creature Gollum, has put on a ring which makes him invisible and now finds that Gollum is standing between himself and the exit of the goblin kingdom. Bilbo has every opportunity, let alone the right, to kill Gollum. But he doesn't. This scenario repeats itself in the Return of the King, where Gollum has attempted to murder Frodo and Sam, and Sam, who has despised Gollum from the moment he saw him, has the chance to kill him. But he too lets Gollum live. While it is perfectly 'logical' that the world would be better off without Gollum, the characters come to the same conclusion that it is not right to kill him.

2.It challenges a popular (often twisted or confused) worldview.
This world is Messed Up. It's been that way for thousands of years. A lot of famous authors wrote about it in fictional stories, such as Oliver Twist. This book is actually based off real facts about the time that Charles Dickens lived in. It was so accurate, that Queen Victoria's advisers didn't want her to read it! (But she did.)
And I know that Frozen doesn't really count as literature, and everyone's tired of it, but it fits this theme.
It reminded people that (A) true love doesn't always mean it's romantic love, and (B) the first man you meet, even if he seems perfect, may not be 'the one'.

3. The characters are connectable.
People enjoy being able to understand the characters. I suspected that whoever wrote The Lions of Little Rock was video-taping me when I first read it. It was awesome.
In Pride and Prejudice (If you haven't read the book yet, watch the 1995 film first) we enjoy watching the different personalities unfold into memorable characters, from the witty and critical Elizabeth to her sister Jane, who refuses to believe that anyone could be truly bad.
It's also interesting to be misled by first impressions, only to find out that a character who is said to be proud and selfish is actually shy and kind, and another character, who appears to be charming and mistreated is actually sinister and conniving.
If people don't connect to the characters' personalities and feelings, the story won't click.

4. It shows true change and/or redemption.
It's a relief to know that no matter how far we go from good, there is a way back.
Just as long as these don't go to the now cliche 'prodigal son' allegory, we're good to go.
(Come on, you know what I mean. Good family, bratty child. Bratty child goes into the world to make their future, friends prove to be false, goes back to good family. The 8th time around is pretty annoying.)

 5. It fulfills the basic virtues.
The basic virtues are known to everyone. We don't have to be taught them. Courage, kindness, honor, gentleness, love, peace, hope, etc. You get the idea.
