Gaiden already was animated. I think between episodes 19 - 23
Ignoring Shoujo Scenes, i think the Last pretty OOC, especially Naruto and Hinata's character .
Hinata risked her life to save Naruto and said with all words:
"I love You"
Neji's death and the Hand Holding scene is Naruto finally acknowledging Hinata, like SasuSaku forehead poke .
But come the Last and Hinata is the same shy girl, Naruto is still ignoring Hinata with some ridiculous excuse:
"I Thought you loved me, like i love Ramen"
Pierrot pratically ignored NH manga story and make their own NH's version with the Last
Honestly Naruto inst that stupid...
