So, you can understand the fear particularly if when someone tries to address it, the fix may make the movie worse.

We Have The Technology To Fix This

It is what you do with it.  Particularly with a movie which comes together in parts and often is created from a script which in turn came from a far longer book the opportunity to screw up is almost certain.  Generally, what separates a good movie from a bad one is a combination of skills, focus, and the ability for the director to have a decent vision of what a successful outcome will look like.

What surprises me is how often directors seem to guess at this.  You could certainly survey readers of a book and find out what parts of it they would particularly love to see on film providing you with a better sense of what to keep and leave out.   Using a game engine, you can even do a pretty good job of creating an emulation of what the movie will end up looking like with the lines in place before firing up the first camera or drawing the first real cell.   You could then test the result to see if the vision works with an audience.   This might help you with actor selection as well because you could digitally change out the actors in the rendered trial movie and tune it.  Here is an example of the amazing quality you can get out of a game engine, in this case Unity.
Wrapping Up: 

There is no real excuse for creating bad movies.  There are methods that can be used to emulate what a movie will become and correct issues with actor selection, staging, and scripts before the first frame is shot or before the first animated cell is drawn.  They likely aren’t used because of an excessive focus on meeting deadlines and not enough focus on assuring quality of the result.  This doesn’t just exist in films but with every product category ranging from cars to cell phones.

With digital emulation, we can create a reasonable facsimile of virtually anything be it product, building, or movie and as most have found out, doing so results in a far better, far cheaper, product creation process.  This is because mistakes are caught early and timelines and quality can be better assured.  Why we haven’t taken these steps more aggressively is likely because folks would rather avoid bad news than they would seek it out to correct the related problems.

Good news is the industry is likely going to figure this out, bad news is it won’t fix the movies coming out this weekend
