Personally, as a fan of Tolkein's works, I thought LoTR was fine. I didn't necessarily agree with all of Jackon's decisions, but, in the end, I enjoyed watching the movies (and still do). The Hobbit films are a different beast, for sure.
Exactly my opinion as well. What worries me is that we saw what ten years of market shift did between LotR and The Hobbit. Now it's been another ten years of it. Instead of showing bad people tearing down trees to fuel industry, we're going to have some good character give a five minute long speech about it. There is going to be a romance plot between an orc and a non-orc. There is going to be a female orc and she is going to be a strong independent woman. There is going to be a ruler who is as bad Denethor but they're going to make a strong point about him also being a racist.
All of the classic stories we tell kids have evolved over time and are no longer true to their original source material. We take the thing we need, ignore the things we don't need, and add what's missing from our modern eyes.
If you go back to the source material for things like Snow White, Pinocchio and trace them through the ages you'll see that they have constantly changed and adjusted.

What he got wrong is that they're perfectly fun and good films in their own right - it'd be more accurate to say they're heavily inspired by the LoTR books rather than being direct adaptions. In some cases they cut things which just would never have even worked on screen, and in general I don't think a deeply ponderous and weighty mood would have really been received that well. That said, some of the changes they made (e.g. to Denethor) were just gratuitous.
My number 1 gripe was the army of the dead being the deus ex machina making rest of the battle pointless joke. This is after making perfect entrance for Rohan
I like the movies and enjoy watching them, some parts are masterpieces but some not so much.
But they are not “an army at the ser ice of Aragorn”. They just want to be liberated and to do so, they fulfill the promise they broke. They are not obligated to more (and Aragorn has no power to keep them “here”), much less to make them obey him.
