(via Miscellaneous Heathen)
For the humor-impaired or those who don't have time to read it, most of the items on this list are meta-parody. Except for the following, which appear to be genuine (though still sarcastic) criticism of the movie:

• The mutated muscular soldiers of Mordor turned out to be hilariously ineffective fighters, a dozen of them held off by a single dying human. Apparently they made the beasts by crossing Orcs, Goblins and the French.
• The most advanced civilization is that of the elves, which are long-haired, new-age types? Sorry, Mr. Jackson, but modern science has proven that in any modern civilization, hippies would be extinct.

This strange stylistic shift proves that either:

• The list was written by more than one person.
• The author suffers from multiple personality disorder.
• The author is sloppy, careless, or clueless about writing. This is hard to believe about somebody anal enough to even make such a list, even if it is a parody.
• These are part of the meta-parody, because the author actually likes hippies and France. This is also somewhat hard to believe.
• The stylistic inconsistency itself is part of the meta-parody.
