The only thing that really stuck out to me in my recent rewatch was the sequence where the set of stairs falls over in Moria. Looks like something out of the PS2 game.
Ah yes the close up also where they fall towards camera clearly blue screen or green screen.
There is a very computer game like quality to some of it. It is exactly something like that i would stamp update on you could possibly remove this sequence entirely to be honest.
^Thinking about this part of the film some more here is another goof watch this abandoned sequence.

Now after this part we are to get the bit where Legolas says “We are in your debt” which makes that whole line make sense now because of the rescue from a boblin horde. I am wondering if they are in lothlorien already when this line is spoken as it is on the lothlorien set then after this they are walking and are shown Lothlorien trees Cahadras in the distance… Feels very messy here possibly all the reshoots and shuffling.
Bear in mind this would have been color graded to be at night. Take note of switching day to night a lot here.
And the Cave trolls opening the black gate of Mordor they look half baked in two towers.
