I bought the theatrical versions a while ago because I was able to get them for $9 a piece. I enjoy the extended editions, but I don't need them. When I watch LOTR, I have a habit of wasting my entire day away in front of the TV watching all 3 of them; I don't need them to be any longer than they already are!
Agreed. The extended versions do explain things a bit better, but I'm just not enough of a LOTR fanatic to want to sit through them ever again.
The theatrical versions are already good enough (and long enough) for me.
