Certainly no hard feelings Guillem.
Though yes, I do think PJ did his best work when he had someone (or rather many someones) reigning in his worst instincts. That's not unique to him - that's a standard facet of humanity, and especially to creative professionals.
It can be near irresistible once you're in the thick of building something to think "you know what would be SO COOL?!? What if we....."
Writers do it. Actors do it. Heck - programmers do it.
The problem is when you're down in the trenches creating rather than up at the drafting board planning you can easily lose sight of your big picture.
Moreover, when you're creating in someone else's world, their vision is part of that "big picture."
It is SO INCREDIBLY EASY to let your own "this will be SO COOL" instincts override not only your vision, but theirs.
But what seems cool in the moment is a distracting embarrassment in the final project, because it's in glaring contrast to the actual vision you started with.
(definitive example: PJ's run-from-the-pile-of-skulls gag in ROTK)
This is why writers say "kill your darlings." That is why (good) writers have brutal alpha readers who aren't their friends go over their work prior to the work of final editing. That is even why programmers have code reviews.
And that is why good film adaptations don't let a single hand get everything he wants, no matter how talented he is.
As to Born of Hope - I recall watching it some years ago and being pleasantly surprised. The acting was a bit cringy in places (as is the case with pretty much all fan work) but by and large remarkably well done all things considered.
edit - rewatching bits again, I'm astonished how well written the language of the dialog is. It feels spot on to Tolkien's text, at least at a casual listen. Really impressive for a modern performance!
