Overall, Stellvia is a first rate anime that's definitely one of my favorites. From the animation, to the character design, to the story, Stellvia excels in portraying a great sci-fi slice-of-life story.

Stellvia was one of my favorite series from 2002, and I think it was mostly because I, like Katase, liked programming a lot. Katase's propensity towards crying when she can't solve an issue (which happens rather a lot, especially in the beginning of the show) puts off a lot of folks who can't stand a whiny, crybaby type. Indeed, I found that to be quite annoying, but I enjoyed watching her and the others around her grow and have to deal with growing up into adults. Katase and her friends were able to mature past many of their early character faults, in many cases forced to due to extenuating circumstances. I found most of the interactions between people felt real and genuine despite the fact I was watching celluloid (or computer-generated pixels).

Overall this was one of the best produced anime's I have had the pleasure of viewing. This anime is full of every element that one could want in an anime drama, romance, action, and comedy.
The story is very original and is something I have not seen before nothing was takin form other animes and there weren't any bad puns of any sort throughout the whole of this series.
