Not really PJ's fault.
He took over an already existing project with strict deadlines.
He didn't have the opportunity to spend 2 years doing pre-production.
Cringy Love stories is fine if Tolkien's canon had cringy love stories.
Like, LOTR's love story was a bit cringe. But people loved it anyway because it was actually Tolkien realistic.
In Appendix of ROTK, Arwen literally saw Aragorn walking up the hill after not seeing him for 28 years, stared at him for a few seconds and immediately decided that he was the one and she would sacrifice her immortality for him.
In Silmarillion the cheese becomes even stronger with stuff like Thingol disappearing into the woods after getting Lost, bumps into Melian and the two of them stare at each other for over two centuries completely in a trance mesmerized.
During these 200 years of them literally staring at each other, the Teleri think their king has died and simply move on with their lives.
