and it's most likely for this, the bond between Tinkerbell and Periwinkle and i can actually relate to this because i have a(n) (older) sister myself, we don't always get along but i don't even want to think about losing a sister over something for whatever happens
i mainly watch this movie for this but there are other things what i love about this movie
Tinkerbell's curiosity about the winter woods, winter clothes on warmer fairies, Tinkerbell dealing with stuff (despite The Lost Treasure being my first favourite, Tink actually handled things better in THIS movie, especially when it involves Periwinkle, Tink isn't as angry like she used to in the earlier movies and she FACED the problems)
the relationship between Queen Clarion and Lord Milori (speaking of that, there's a book coming out by next year based on them, i hope they makes a movie version from the book in the future)
the relationship with Rosetta and Sled, it's like love at first sight for them both and i live for that
unlike "The Lost Treasure" Tinkerbell's friends (except Terence unfortunately) appeared more, they were there to visit a doctor, at the Tinkers nook to work on a machine, when they saw Periwinkle, when they met her, when Periwinkle was in danger, when the sisters got confronted by Lord Milori, the snowmaking machine to push it away (except Fawn and Silvermist), when the freeze have started they got the animals to safety (except Vidia), when all the other winter fairies comes to help to save the pixie dust tree from the freeze, after the freeze was over when Tinkerbell broke her wing and got healed and last but not the least the epilogue scene (i did wished warmer fairies did something to save pixie hollow from freezing, NOT just the winter fairies)
Fawn appeared slightly more then Tink's other friends like she appeared with a bunny and even appeared first before the others, when Tinkerbell helped Fawn with the animals and crossed in that same scene Fawn had to bring Tink to the doctor and last one when she watched closely along with the Tinker fairies and Queen Clarion how Periwinkle, Gliss and Spike tries to save the pixie dust tree on their own during the freeze
i loved how Tinkerbell's friends was concerned for her (even a fairy who used not to care for Tinkerbell untill the human event have happened was very concerned for Tinkerbell and this is showed with the doctor scene, after helping Tinkerbell to bring Periwinkle back to the winter woods and when Tinkerbell broke her wing, this person took it the hardest from like everybody except Periwinkle who was even more upset about Tink's broken wing...you can guess which one i'm talking about)
even Vidia appeared in this movie as a supporter character (knowing Disney or even outside Disney who have a habbit of using characters as a background character after having important role in certain previous movies or seasons) and she stayed in its further movies (even the final movie one but not like it used to like in some other movies)
there are 2 minus and my main bother was Terence wasn't even there just when Tinkerbell needed him the most (and i blame Disney for this, he's literally one of Tink's best friends and i can imagine he takes it the hardest out of everybody when Tinkerbell broke her wing since he obviously have a crush on her, he's most likely the reason Tinkerbell stayed in pixie hollow TWICE so it's only fair to include him as a supporter character instead of using him as a background character) i don't understand why he got credited, he didn't had any single speaking roles, he appeared only 2 times, i really hated that, why not atleast help her with the snowmaking machine or something? or like help Tinkerbell to push the snowmaking machine away? like i understand he had work to do and stuff but he would've noticed the snow in pixie hollow, he's really excluded in this movie (if he can't be in the movie that much, atleast do something like they did in "The Great Fairy Rescue" with a few speaking roles atleast)
my another flaw on this movie are the winter fairies one and the minister of winter, if you watched the first movie you see Tinkerbell, Clank and Bobble flying to the winter woods when giving her a tour on pixie hollow and they had no troubles flying over there and the winter fairies were on the warmer side and they had no troubles there neither, what happened to that?
nothing can beat "The Lost Treasure" movie but this movie is my next favourite, i think this is the highest rank in general along with "The Pirate Fairy" movie, most of the votes goes for these 2 movies and i can't blame them for ranking it higher
