well, I said it was too thick, compared to a real one

I think many parts of the movie were quite accurate, the scene in the Moria, save for the beaffed up troll and a few details, was a real act of bravery if you ask me, and, honestly, I would never have expected the Balrog to look that close from how I was imagining it.
Btw, the female warior is Eowyn of Rohan, and yeah, ARwen picking up Frodo kindda pissed me off. Arwen is not a warrior at all. I kindda like Bombadil tho, he's probably the most powerful creature of middle earth, even if he doesn't look at all this way, but yeah, he could look kindda out of the place. I think he's a Maiar actually. There's no statement against that, and he's not powerful enough to be a Valar (and I think we know the names of all the Valars in the Silmarillion anyway). He's definitively not a wizard, and I don't see any other option. And I doubt he would be a one of a kind creature.
