You'll find as we get higher and higher on this list, there's gonna be a recurring theme of movies I watched over and over as a kid. Get used to it. I really dont think I need to justify my love of The Lion King to anybody. Its so fun with great music and fantastic characters, but its also really dramatic and emotional. Voice talent that is just phenomenal.
Here's another antecdote. Freshman year, my roommate and I are on our way to see a friend in a production of Rosencrantz and Gildenstern are dead. Since I wasn't particularly familiar with Hamlet, on the T ride over the roomie gave me Hamlet 101. It started with something like "So, you've seen The Lion King, yeah?". And this is why I hear Hakuna Matata in my head whenever I see an R&G reference.
