Based on what I can find on the Internet, it appears that the "Motion" statues aren't very good. They either barely move or break easily.
The Minis don't have much detail (which is to be expected give their size).
I know some vocal forum members have bashed these, but judging by the amount of statues that DC released in a span of 4-5 years, it seems that there was a market for them.
There were more Regular Ame-Comi statues than Superman: Man of Steel or Wonder Woman: Art of War statues.
