The 20th anniversary special! Yay! And a rather good special at that! :) Story: What an amazing storyline/plot/etc.!!!!!! Nothing like this was in any of the seasons or specials or ovas before! Very unique and definitey well thought out. Score for AMG. Art: The art is as wonderful, if not better, as the tv series was. I do believe the colors are richer and of higher quality in this special though. Sound: Same as the art. It is just as amazing, if not more amazing, than the sound quality of the tv series. The background tracks also fit really well with the scenes.Character:
Really no time to develop the characters, except for Lind. She is developed pretty good in a 2 episode special and you start to get a feel for who she really is.

Enjoyment:
Although moving slow at some parts, I completely enjoyed this. I could've done without the stupid little "comedy" bits here and there though :\

Overall:
If you have seen anything to do with Ah! My Goddess; the first season, the movie, the ova, the specials, the second season, the manga, etc. I highly highly HIGHLY recommend taht you give this special a shot ;) I just have to warn you now that if you are expecting Belldandy and Keiichi to be more romantical and stuff that this will be a HUGE disappointment on your half.
