If you watch old movie, you start to understand the modern CGI produced movies are having a problem of the movie makers cannot decide what they want to tell the audience, and they start to throwing as much staff on screen and hope they can appeal to most of the people.

In addition to the splash of pixels and colors, the dialogue is hard to follow in modern films, google "modern film voice is hard to hear" you'll see that's a common complaint.

The last batch of movies that do not suffer these are LOTR trilogy, and the matrix (not the sequels). Then from then, I cannot recall any film that has a clear idea and is keen to focus on the idea and develop the film accordingly.
