YMMV: Galilei Donna
- Counterpart Comparison: The series has been compared to National Treasure or a Dan Brown novel. With Humongous Mecha.
- Critical Research Failure: This person's blog post about episode 5 and all of its errors about the Netherlands pretty much speaks for itself.
- Heel-Face Revolving Door: As in Episode 8, Anna seems to be going to hit this.
- Tear Jerker: Episode 5: The deaths of Theo and Karen. What's even more tear breaking is that Hozuki tried to risk her life to save both of them, but Grande Rosso took control of the ship and forced Hozuki away from them to prevent the rescue because of a large probability of being shot down.
- They Wasted a Perfectly Good Plot: Many fans felt that the last episode was rushed and didn't adequately resolve all of the dangling plot threads set up in the series.
- Wangst: Kazuki basically breathes this in episode 3, with her constant "I'm jealous of my sisters" whining. She gets over it by the next episodes or so.
- What Could Have Been: The writers had already planned its storyline to run over more than 20 episodes. And then Aniplex asked them to cut down its length.
- The Woobie: Hozuki, with everything the poor girl has to go through (see the Tear Jerker entry above). She also wants Kazuki to like her, even though Kazuki thinks otherwise.
