A few friends are already planning a LOTR day in my HT as soon as I get these.
I did that with the extended editions on DVD a few years back... I posted all about it on here way back when...
Long story short: It was very painful (literally) to sit for that long. Even with many breaks throughout the day.
you say "painful"! you're right.
when i got the 3 LOTR Extended version box, i watched the 3 parts and then went on right away to watch every little docu. on the discs, including the running commentaries on the movies themselves.
i guess it took me around 7 days to see it all.
since then, i've watched the movies about 12 times, but not because it's THAT good, but because the whole thing is so long that when you see something in the 3rd movie that links with something in the first one, you can't remember what it was, it's so long ago...you've forgotten.
it's true that for a while now my memory isn't what it used to be. (I've heard that before!).
