Uchuu no Stellvia

• Drama: Med/High (characters questioning their self-esteem being a main part of the story, and humanity on the verge of extinction)
• Comedy: Low/Med (at least as many funny moments as depressing ones)
• Action: Med (space ships in action, plus interstellar disasters)
• SciFi: Med/High (science being the means for humankind to survive a catastrophe scheduled 189 years ahead... plus the alien interference element)
• Ecchi: None/Low (schoolgirls of age 12-16 in short skirts, nothing beyond shy kisses)

• The academy's server is frequently hacked by prep students.
• Rule violations are never punished (this highly equipped space station is more like a kindergarten).
• It's sheer nonsense to arbitrarily limit the team of pilots fighting against the Second Wave effect to a fixed number instead of accepting everyone who qualifies by a common test, given the large number of available machines and being short on personnel.
• Laws of physics, most notably for spaceships colliding with each other in high speed, are constantly neglected to an extent that borders the ridiculous.
• If the effect of the Great Wall is to slow down the approaching objects, then the most likely candidates to break through that barrier are the big objects, not the small ones, and their resulting speed after passing the Wall would depend on their impulse, meaning the largest object would be the fastest one... facing the Infi with the issue of being in several places at the same time.
• If the material from the supernova took 189 years to reach earth, and the Great Wall was operated a mere day, this means that all objects had the same velocity with a deviation of less than 0.0015%. If it were me to operate the Great Wall I'd leave it in effect for a couple of weeks, if not months - making the Second Wave much more a war than a kind of sports festival as shown in this series.
• By the way, there's no oxygen in space, meaning that every single hull breach of a space ship would automatically lead to a horrible death of the pilot, given these sexy but useless space suits without any oxygen tank. (And yes, with that in mind most of the fooling around in their training ships wouldn't have been possible, including certain actions by Machida-senpai.)

What I am most amazed is that Shinma did not turn into the all knowing Deus Ex Machine (Like Shinon in Starship Operators did). She has real emotions and real issues. I am surprised that CLAMP didn't write this.
