This adaptation is not quite as good as the original light novels, which are masterpieces (go buy them, seriously! ). That said, this anime is still superb! The big changes from the books are the story arcs are re-arranged and most of the darker elements are removed for a bigger emphasis on comady. Animation for this series is well done; solid artwork thoughout the series, good shaddowing and shading, and little sceen re-use and stock footage. On the Japanese side with Megumi Hayashibara as Lina Inverse heading up the Japanese cast, the voice acting is great. However, the first bunch of English voice acters that are cast for this arn't all that great, but the second set that are re-cast half way through the first season do a good job (Crispin Freeman captures Zelgadis perfectly). Buy it. Watch it. Love it.
