I have decided to abandon the task of showing how Tolkien portrayed Wargs as great in his books. With the merest of glances at
Out of the Frying-Pan into the Fire in
The Hobbit one can plainly see that Tolkien thought highly of Wargs. Thus, the self-appointed task would have been a pointless endeavour.
It strikes me now that what Tolkien dismissed from his works was the cultural aspects of Warg life. This can probably be explained by the fact that
The Hobbit and
The Lord of the Rings were written about times of War and not peace or plenty. Also, he had spent too much time building up the beauty of the Elves to overshadow them with Wargs.
And let's be honest, Legolas is going to be a much more appropriate poster-boy for the desired movie-audience than any Warg.
