What's wrong with this picture?

Let me first say, I was a big fan of 'The Lord of the Rings' and 'The Hobbit' while growing up, and have overall enjoyed the movie versions. A few things have bothered me though. I noticed these things starting with 'The Return of the King':
1. Why is every battle scene a handful or few versus and endless number of enemies? I feel like I'm watching a video game and not a movie. Can't it be just a little more realistic? Maybe a few versus a few more?
2. Why do most of the Dwarfs, Hobbits, Elves, etc have capped teeth?
3. Why does the new female character have Hollywood lips? She looks like she got stung by a bee.
Make me be part of a journey in an earthly world, not part of a video game.
