It’s not based on a Tom Clancy novel. It’s clearly not meant to bear any resemblance whatsoever to the actual Jack Ryan timeline the books established. So it’s just another action movie. It’s directed by Kenneth Branagh, so it’ll probably be a pretty good just-another-action-movie, but c’mon.
If they really wanted to do something different, here’s an idea: Jacqueline Ryan.
The thought that really bugs me is this: The Hunt for Red October, one of the greatest thrillers ever made, could not get made today. It would be considered too thinky, too talky, not actiony enough.
