[Tuor of Gondolin]

Two brief points:

1) PJ's changes frequently make little sense, even in the 3 movies internal story logic, save to get more immdiate "action" and plot resolution. Consider the
biggest movie travesty, Gandalf (twice) mugging Denethor while Denethor's elite guards do nothing, the guards disinterest is ridiculous even forgetting this absurd treatment of Gandalf's character and the mandate of the Istari not to interfere or dominate Middle-earth peoples.

2) In the TTT, it's Wormtongue's thugs that are attacked by Leggy and friends,
Theoden's guards were prepared to whack Strider, Gimli, and Legolas until Hama restrained them.
