Since other reviews have discussed the series in detail (plots, characters, etc.) I will only add that this series should be experienced as a whole, and not piecemeal. Watching the series out of order or only getting a few of the episodes will only lead to a disappointing experience (as well as confuse the hell out of the viewer). If you are truly interested I would recommend getting the entire series as well as the two movies, Death & Rebirth (2 hour recap with some new footage that leads into the final act) and The End of Evangelion. Actually, the series won't make as much sense without watching End of Evangelion (which is incredibly surreal--big mindtrip!!). This series is less of a shoot-em-up then some preview footage may lead you to believe. If mature anime is your thing, I would highly recommend this series. If you don't like to think about metaphysical and psychological topics and have a short attention span (i.e. you don't want to have to think about the possible meanings of the show) then you might want to save you money. Otherwise, this is about as good as anime gets.
