I think this movie is waaaaaaaay overrated. Hated the fart humor, the flat dialogue,the violence, the absence of any individual character development (especially in the female lead-- where were the ladies in this film?), the damn Hakuna Matata song, the "circle of life" crap, the obnoxious Yoda ripoff monkey, and did I mention the farting? The only cool thing was James Earl Jones doing the "Who's Your Daddy?" thing again-- and that wasn't even original.
Your milage may vary, of course.
Speaking of doing well financially, this was the highest-grossing film of the 20th century. But if that's your measure of what makes a good movie, I have one word for you: Titanic.
