I rather enjoy the Bruce Willis/Helen Mirren movies 'Red' & 'Red 2" ... comedy with serious drama blend.
The problem with many modern movies: too much focus on winning awards & making money. Great epics, like the movies you cited, [MENTION=89648]Meatballsub[/MENTION] , couldn't be made today because of the cost. The typical audience wouldn't want to sit through three hours (without including intermission) of an epic like "Gone With The Wind" or "My Fair Lady".
Back in the studio days, the studios kept their actors/actresses busy. It was nothing for top A-list stars like Bette David, Clark Gable, etc, to make several movies in a years' time, while many of those on the B list made twice as many. By having a constant flow of films for theaters (which the studios either owned or helped finance), there was money being made on a steady basis. In addition, the studios also kept their A & B listers pidgeon-holed in categories the audiences expected. Bette Davis was a femme fatale ... Myrna Loy was rarely a bad girl ... and Doris Day was America's sweetheart. Today, without being held back by studios, actors/actresses try different genres, sometimes to the great disappointment of their usual audience.
Anyway .... it took a curious amount of shopping around his script & ideas, starting in the late 70s and early 80s before finally Steven Spielberg's "ET" was financed & had a studio to back it. Another example was George Lucas' "Star Wars" ... took a bit of time to find backing; too many thought it would be a re-make of Star Trek & no one wanted another cheesy Captain Kirk.
So today, we see Brad Pitt in "WWZ" (which doesn't resemble the book at all, with the exception of the name of the lead character & one other detail), which didn't last long, even though it was a big zombie movie - again, an attempt to cash in on the zombie fad. There are far too many modern movies I wouldn't allow my kids to see, if my kids were young enough to be minors & at home.
All I can say is I'm glad there were studios who made many of Michael Crichton books into films .... Andromeda Strain (in which the author has a cameo) ... Sphere ... Timeline ... Jurassic Park, Lost World (much of what was in Jurassic Park III was from those 2 books) ... etc.
