I remember watching all the extended versions one night... I kinda sucked though, because I think I miss half of the Extended parts (zzzz) 8 pm to 5 pm is a long haul. My folks weren't Happy.
Everyone makes Helm's Deep (not that it's a bad thing) But a Minas Tirith, Minas Morgul, Osgilitath, or the Black Gate would be cool too.
