At this point everyone has come to know and love all of the characters, and the stakes have become tremendously high. Kingdoms are at their knees, and the only two characters who can save the day are getting weaker and weaker. The tension was very high in this episode and I can honestly say that out of all 3 this was the only one that had me on the edge of my seat. There were many memorable scenes (one of my favourites including the part with the giant spider)that made this the classic that it is sure to stay for decades to come.
This is the longest of the series, mostly because of the ending that seems to last a while. This was a good ending, and I can see why Frodo did what he did. He, and us the audience, have gone through an incredible ordeal and I think we needed that 20 minute linger. When the battle is over, and the celebrations have ended, there is a sad emptiness felt. The films spanned over 3 years, there have been the extended cuts of course, but after that, it's all over. Peter Jackson gave us an ending that was both appropriate and admirable.
These were some amazing movies and this one in particular is the best, in my opinion. As whole, the Lord Of The Rings is a phenomenon. An absolute phenomenon. Much more than just movies. They have a universal appeal and have touched the hearts and imaginations of millions. I'm one of them.
Sorry if I'm being all fanboyish and kissing this movie's ass, but I really admire it. It may not be among my personal favourites but generally this seems to be the movie event of the century. There will never be another Lord of the Rings film, and that's a bit depressing
