I've only been five times, but one of my sisters has been 8 or 9 times! Of course, she's still being homeschooled so has more free time than I do off at college.
I'm lucky - my Dad was a huge Tolkien fan and so I always had someone to talk to, though I don't suppose my comments, as an 11-year-old, really were that intuitive. Now both my little sisters love LotR, and all my friends are obsessed too! I tell you, it's a great time to be a fan. You think Mr. HobbitholeBoy will give tours if you ask him nicely?
You were blessed with your dad in that way. I love and miss my Dad very much, but he shared almost none of my literary tastes.
Happily, my wife is a big fan, and was long before we met (as was I). We're on about our 4th read-through for our marriage. She was critical after her first viewing because of the changes and omissions, but now is a 6-timer and such a big fan that she successfully bid for the complete set of LOTR action figures on E-Bay.
For herself, not the boys! (c8
