As unfortunate as it is, studying cause-and-effect is extremely complex. If it's even theoretically possible to distill it down to easily digestible ideas, that's well outside our current technical capabilities.
There's usually going to be some true and interesting information in these books, but it will be too deeply embedded in a narrative that is misleading.
I have already come across books that were a slog to read because of the author's simplistic worldview or obvious contrarian agenda (so I can definitely relate), but I've also read some masterpieces (for example, Kaldellis I believe is solid).
Unfortunately I don't count any historians among my friends, so I'd welcome any recs from you for authors that are the least bad, or a teardown of main antiquity/middle ages historians.
