Hi guys, since I had compare both Titanic and Frozen. There is another movie that I notice that is similar to the latter, and that movie is Brother Bear.

Brother Bear

Apart from the sibling love, Kenai actually reminds me of Elsa, because like Elsa, he needs to have brotherly love with Koda. He was also mistakenly thought to be the same beer in his brother, Denahi's eyes that killed his 2 brothers and became vengeful until the ending scene when Kenai gets turn back into a human.
Koda is very much like Anna, because they're both optimistic. It wasn't until that he found out the truth that Kenai murdered his mother at the beginning of the movie, that scene was really emotional for everybody to watch. It reminds me when Hans betrayed Anna and I felt sorry for both the latter and Koda.
The muziek was really underrated, however the songs have meanings in them. Especially 'Look through my Eyes' and 'No Way Out, the latter really works for Elsa's personality herself, in fact it should be sung as a duet with her sister, Anna!

Frozen

Like Brother Bear, this movie also deals with sibling love. It reminds me of the mentioned movie and they are very emotional, especially the story-line itself. The songs are the opposite, it's very populair especially the Godly overrated song 'Let it Go'!
But, one thing good is that these 2 films teach us about love and forgiving. Whereas Brother beer is focus meer on learning new things along the way, Frozen is meer on letting go despite that they share some similarities.

Conclusion

While I love these 2 movies, it will always remain as 2 great Disney films in everybody's heart.
