We're talking at completely cross-purposes here, you're talking about technical bugs and glitchs, i'm talking about the flat empty World. I don't agree that this is just the fault of the director either, this is a massive creative failure. It is a lack of vision, ambition, creativity and care from the outset, in total contrast to PJ's Trilogy, he wasn't solely responsible for creating a truly believable lived-in realistic World either, there were dozens of artists, designers, people building sets, hands on artisans creating armour etc with incredible attention to detail.
LOTR was a massive collaborative effort with a cast of hundreds of talented people with a shared vision, RoP does not have the talent in any area to match LOTR, and this is why the World is so dead, unengaging and lacks believability.
