Combine "samurai warriors" with "basilisk kouga ninpou chou" and you will get this cursed, ahistorical abomination of the movie which only saving grace are obviously high production values, direction and acting.

All wasted on trash "story" portraying historical characters as exaggerated caricatures straight out of samurai warriros so if you played that you know what to expect (mitsunari obsessed with justice, sakon being a cynical war veteran with scars on his face, etc. ), ninja with superhuman abilities who seem like they came from a shounen manga, and all kinda events that simply speaking never happened....starting with the beginning scene where hideyoshi met mitsunari as a child in a temple, which is just an apocryphal rumor, and in reality he first met mitsunari when he was already 18. Or the scene where Kiyomasa Kato wanted to kill Mitsunari, but the latter found refuge in Ieyasu's mansion, portrayed many times as a stage in samurai warriors and completely untrue to history as Ieyasu didn't have any mansion there and likely no assassination attempt even happened there.

This movie is shilling Mitsunari side, and they overdid it hard. I dislike how they portrayed Tokugawa Ieyasu as a complete villain, while writing Mitsunari as a saint. Even his mistakes were because of his good nature.

For example, in the movie he wasn't caught by peasants while trying to run away from the battle. Noo, he was cared for by them and then refused to leave even when the villagers advised him to when Tokugawa troops approached, because he feared the villagers will be executed for helping him and he would rather die then fail to repay his debt to the villagers. Of course, there is zero historical evidence for that, it's just one of many examples of the author wanting to paint Mitsunari as a kind hearted idiot rather than a cowardly villain.

There were also sus moments of technical nature: teppo firing twice in one scene, flat wooden shield stopping a teppo shot, blind yoshitsugu fighting with a spear, crossbows in sekigahara, ashigaru training with swords and shields, and sus amounts of swords on battlefield that should be dominated by spears.

That being said, could be worse: armors weren't paper here, and they actually had to aim for openings in armors to kill their enemies. Overall, individual fight scenes were well done. The group fight scenes weren't so bad either: soldiers actually fought in formations, although chaotically. The blood looked good, and the weapons and armors looked real.

The music is fine but nothing special. The entire romance between Mitsunari and fictional ninja girl was pretty much non existent, so the genre romance is misapplied to this movie.

As many other people said, to understand what is going on here you need to know of the events portrayed in the movie, as well as who is who, as the movie itself haphazardly jumps from one scene to another without explaining what is happening and why. And as I said before, because of various historical inaccuracies and "alternate" interpretations on these historical events, I wouldn't recommend this movie to people who want to learn japanese history.
