Not to understate what Disney did, but I feel like most of their characters don't have much depth.
I recently rewatched 12 angry men, and was surprised at how quickly and efficiently they introduced 12 characters. Off-hand remark by one character, an expression by another, the way they stood and moved around; in around 5 seconds you knew the characters without even knowing their names.
Contrast to Marvel's characters, which have hours of development each, yet don't really feel alive. All of them have tragic backstory, all of them are heroic in the same way, most of the male characters are snarky/sarcastic/have big egos.
