I have bought the unrated HD version of this trilogy, and the first thing I want to point out is that they are not HD as advertised. The image is not that crisp to begin with, and it deteriorates significantly if I zoom in on it.
As for the films, well, a good part of the dialogue does not make any sense unless you have read the books to fill in the skipped parts, or your friends who have read them will tell you how in the world something came to be.
Just a couple of examples: on Fifty Shades of Grey, what led to Christian's belting Ana at the end of the movie? In the book, Ana woke up, Christian was playing the piano; they talked; she teased him by running from him; he got mad because she could fall and get hurt and for making him wait. In the movie, they made sweet love before sleep and he woke up seething like an angry beast, wanting to punish Ana for heaven knows why. On Fifty Shades Darker, how did Leila know that the car she destroyed belonged to Ana? Well, because Christian was such a doofus that he bought the woman he is in love with, whom he considers so especial and different from the others, the same car he gave all his subs.
In short, these famous Hollywood film makers made tons of money being as thorough as a bunch of second graders would have been, skipping parts of the story with no regard for continuity or meaning. Incidentally, viewers do not mind because, mostly, the movies are just long infomercials showing how easy and fun life would be if we had money to burn on expensive superfluous stuff and all the time in the world to indulge in our pastimes. As if all this wasn’t enough, just like the books, the second and third films are progressively worse than the first.
