I think it's strange too, the fawning adoration of Disney, but it doesn't seem to be particularly uncommon. I belong to lots of moms groups and there's always at least one or two big Disney fans around. I hope I am not offending anyone by saying this. I think I have a disconnect from it because Disney seems so obviously...crafted to be commercial, to be sold and bought. There is a certain charm and artistic merit to be found in the older movies ("older" to me means older than The Lion King, haha) but these days it's pretty much a money machine. To me it's like being obsessed with Wal*Mart or something.
This is coming from someone who is a hyoooog fan of a 90s band and still gets giddy with schoolgirl glee watching their music videos from the good old days, so I understand irrational obsessions.
