Which Annie's did you see? If you're not comfortable stating names, which years?
Back in the day I thought each Annie was very different from one another. Each actress brought something completely unique to the role. Same for the orphans e.g. no Tessie said "Oh my goodness!" the same way but each was cute and funny in her own way.
I found the 20th orphans robotic, though, and even the 30th. But that wasn't from lack of talent. It was poor direction, imo.
