Basically, it's a continuation of the first series, and not much happens. There is very little progress in the relationship between Keiichi and Belldandy -- obviously the writers (of the manga) don't want to reach any sort of conclusion, because then obviously the series will end...
So the initial plot of the series revolves around Keiichi and Belldandy (which involves another rather scantily-clad goddess...), but then the focus shifts away from the main couple towards the other characters. And while those stories are enjoyable in their own right, it does nothing to advance the plot. The best we get is that Keiichi tells Belldandy that he loves her and wants to stay with her. Frankly, that's a bit meagre.
The series is still fun, though, but not as funny as the first one. Where the first series had the whole gang together almost every single episode, this series is much more 'fragmented'. That allows some more in-depth views into the lives of the others, but since it plays out in a 'perpetual status quo', there's not much progress there either.
The quality of the first series is apparent in the second series as well. Same voice acting, same animation quality: all very good.
- More of the same, if you liked that;
- Still technically perfect;
- Shows more of the secondary characters.
- Perpetual status quo: no progress anywhere.
That last one really did it for me. It's doubtful I'll watch a third series, if that ever gets produced. But for what it is, this one deserves a 7.
