It's not about the audience being able to "handle" it, they just realize there's a different scope they can reach with a TV show that can't possibly match the books. Some fans should realize that too.
There's no point in presenting everything with the same level of detail, it could easily be done but it would just dilute everything and make it weaker.
I was mostly just joking around with all of that. I think they could have handled the Thenns better, though. Having them mostly talking in a foreign language aside from already having the bald look would do a perfectly good job of capturing the Thenns status as being slightly different without either having to get into all of the finer details of their culture from the books or making them cartoonish cannibals.
