I've always found ANNIE to be a very medicore show in general. If anything, the 80's movie elevated the material.
It actually didn't, though. Two of the most important songs from the stage musical were cut from the the film. One was "NYC", which is when Warbucks reluctantly takes Annie out to a movie - they decide to walk ("It's only 27 blocks!"), and in giving Annie the tour of the city, that's when they actually start to bond beyond the publicity stunt this originally was supposed to be. Later, she's too tired to make the walk home, and he picks her up -with a funny moment where the kid is dangling awkwardly in his arms while he tries to figure out how to do that - sings her to sleep and carries her home.
The 1982 scrapped that song and replaced it with "Let's Go To The Movies", which isn't about Annie or Warbucks at all, it's a random tribute to the Golden Age of Hollywood. It's a nice production number, but it means nothing to the story, especially when at the end of it we're stuck watching about 5 minutes of Camille for some reason.
The 1999 TV movie
put "NYC" back in, and did a much nicer job than the 1982 movie did.
The 1982 film also dropped "Something Was Missing", which is a huge moment in the stage version. That's the scene where Annie's at her lowest, and while Warbucks stumbled the first time he offered to adopt Annie, this was the moment where he got it right, and it's a beautiful song, with a father/daughter dance to go with it. They only cut it because Albert Finney couldn't sing it.
And they screwed up "Tomorrow" in the movie too. Like it or not, it's the show's iconic song, and they ditched in favor for not one, but two songs about the dog.
It rebounds a little with the White House scene, but rolling it like an afterthought over the opening credits made it look they couldn't be bothered having it as part of the movie at all (and I've read they considered cutting it entirely). And again, like it or not, "Tomorrow" has to be a centerpiece if you're making a movie musical out of Annie.
I grew up with the 1982 movie, and I love it for what it is - the finale is better than the stage musical, I love that they gave Warbucks and Hannigan a song together, and Aileen Quinn was miles better than Alicia Morton in the 1999 film. But I can see where the stage musical fans get so frustrated about with it.
