Ok I'll give my review on your ninajgo fic here. My critic is. The characters are way too many like you just shove all the characters down and they appear out if nowhere. Theere is a severe lack of reactions to everything, even at the interesting moments or dialogues, THERE WERE ZERO REACTIONS. There's no depth or emotion in their reactions and comments!
Its just so lacking, no offence. The reactions are too few and bland.
And doesn't the "she" the samurai already supposed to know all of this, being from the future in all so why is she THERE reacting with them, she has no reason to. Also the samurai is "her" rigth?
And lastly is the dialogue, its very off putting to read the narrative and the reaction dialogue mixed together.
The only I can positively say about this is that you managed to do all thes seasons and is still going. So points for this.
I know I'm sounding very rude rigth now but there is a very lare room for improvement.
