What annoys me about Tolkien is that in his books really all races are Dwarves. Even humans, who are also very greedy. Halflings are literally superdwarfs, their advantage is literally exceptional endurance, and they eat a lot. And elves are very busy enjoying material pleasures, too. So, everybody is a dwarf in Tolkien.
And, since I'm personally not exactly into dwarves, I dont like Tolkien that much.
Your knowledge of Tolkien is clearly exhaustive.
