Anastasia, how are you?
Hi guys, okay since I'm a fã of both films. So here are comparisons on both films.

The Story

While watching Tangled, I notice some similarities with Anastasia. Rapunzel and the latter are both lost princesses who would be a commoner for the majority of the film.
Unlike Rapunzel, anastasia suffers from amnesia while falling of the train and losing grip of her grandmother while escaping the revolution, while Rapunzel was kidnap as a baby por Mother Gothel.
They find true amor along the way, and they did not get on well with Flynn and Dmitri respectively. But, as time goes por their relationship blossom. Flynn was knighted in the end for finding Rapunzel, whereas anastasia and Dmitri elope together.

The Characters

Why I said that anastasia and Rapunzel are similar is because they want to know about their past, and not to forget that they are adventurous and intelligent. Especially during the train scene when anastasia helps Dmitri coming up with a solution!
Mother Gothel looks like the female version of Rasputin, mainly because of her appearance. But, Mother Gothel did not reveal her true nature until the segundo half of the film. While Rasputin was very straightforward, he was a villain at the beginning of the film.
Flynn is like Dmitri, because they had a awkward relationship with both Rapunzel and anastasia respectively until gradually they realise their amor for each other as the movie proceed.

The Music

Both songs and musical scores from these 2 filmes are memorable, anastasia reminds me of Alan Menken's work because of how similar they are. It is in fact, compose por David Newman.

Team Rapunzel or Team Anastasia?

So there you have it, do you agree my observations?
Greetings you guys!
