I have 128 total. There are some that I know I didn't see because I am not a fan of some of the of the sequels (i.e. Cinderella and Lion King). Other I have seen sequels (Toy Story).
I checked 398, those were the ones I remember, sure I've seen others (plus I got tired of checking them off.).
WWoD ran from 1954-1992 and a lot were on there. Then with The Disney Channels, going to the drive-in as a child and adult, the theater, DVDs, VHS, me as a child, the much younger siblings, kids and grandkids I think I've seen most of them. Crazy enough we have all of the classic and newer classics to be in DVD etc....
I was in the 150 range. There was a lot I did not check from when I was growing up that I probably saw, but don't remember. Seems like the only movies we ever watched back then were Disney. But that was a LONG time ago!
