I like A!MG actually...but only because the author realized the main couple wasn't all that interesting anymore somewhere down the line and started giving the side characters fun and amusing stories.
For instance, the plot of the Fighting Wings OVA is actually a little similar to what Urd went through earlier in the series, except Urd almost destroyed humanity when she did it
It's like Star Trek DS9, and Keiichi and Belldandy are the space station itself
