Like all Great Classics, it's worth everyone's while to see these films.

Rating: 10/10 (25 August 2004)

I tend to find that the people who have not seen these films yet are people that assume they will not like it, or feel intimidated by its epic scale, running time, and/or feel turned off by the fantasy genre in general.
Do not let this deter you from seeing these films, they are definitely worth your time for one viewing as they are great movies, and destined to be classics. I would go as far to say that they are the best book adaptations to film, but this is, of course, all a matter of opinion. (And as a long time fan of the books, I'm a bit biased).
First of all, I highly reccomend seeing the extended editions of these films as opposed to the theatrical versions. You may want to wait for the EE of RotK to come out on DVD before watching these films. The Extended Editions are simply far superior versions because it more closely captures the pacing, and feel of the books. There is also more depth of character and development introduced in the Extended Editions lacking from the shorter theatrical versions. Whereas the theatrical versions are simple, but good action/special effect movies, the Extended Editions are grand epic adventures that have far more depth and intelligence to them.
Secondly, unless you are watching them for the first at a LotR buttnumbathon type party, I do not reccomend watching them all at once. All together, these films clock in at about 12 hours not including breaks. Your rear will probably be hating its existence by the time you get to Return of the King.
Instead, I reccomend watching it small doses. The Extended DVD Editions split the films over 2 discs and are perfectly designed for 6 90-120 minute episodic viewings. This is the length of an average film, and allow for much less of a time commitment. Still, I reccomend you not wait too long before seeing the next part, as these films essentially are one story with many characters, place names, and plot lines that can be easily forgotten. It's best to watch one DVD per night over 6 nights. Treat it like a really good TV mini-series that you don't want to miss each night.
Lastly, turn off the lights, pump up the volume, and TURN ON THE SUBTITLES. There are many strange words in these films, and it helps if you can see them written in front of you. The films are pretty easy to follow, but the plot is also complex and deep. You will enjoy the films more if you understand as much as you can, as one of the main appeals of Tolkien's story is its attention to detail.
I can guarantee you that if you give these films a chance and take my reccomendations to heart you will not be disappointed. Enjoy.
