So I went to see the first show of opening day of the kancolle movie and I'd like to share my impressions of it.
now I'll try to be as spoiler free as possible but there may be some spoilers so be careful.
So the movie takes place at the Iron Bottom Sound and Fubuki and the gang led by Nagato (Teitoku is somewhere else) have to investigate the strange crimson sea of the iron bottom sound. Basically it's the battles of Solomon.
The movie also reveals secrets of the kanmusu and the abyssals and their relationship. They even show how drops work with the drop of a certain kanmusu after a battle. The movie also shows why Fubuki is so important even though in actual history, she didn't really do anything great.
The animation was great with many of the new Kanmusu (Chokai, Tenryuu, Kako, Furutaka, Kinugasa, Aoba) having good parts in the action. Ships that didn't have much time to shine in action during the anime like Yuudachi and Yamato each had some great action scenes as well. There is also more much less of the Cg and everyone moved like how you expected them to move. Compared to the anime the action is much more fluid with many awesome scenes.
Many different Kanmusu have made cameos and if you listened carefully you could here them talking in the background in some scenes.
Now the story itself might be met with mixed reviews. I won't say anything about it but some people might not like certain events. The story is mainly quite serious with only bits of slice of life. I personally found the story to be quite interesting as it helped with concluding Fubuki's story.
Overall it was quite an enjoyable experience and I can safely recommend the movie to anyone who likes Kancolle. I also recommend people who didn't like the anime to watch this as it fixes a lot of problems the anime had.
