Personally, I was a big big fan of Walgreens Marvel Minimates. The animated waves, that is; not necessarily the MCU assortments.
I felt as if it were the same effect as 'Ultimate Marvel Comics' in the early noughties. Giving fans an opportunity to start a new collection of Marvel Minimates from the beginning in a way which emphasized significant players in the history of Marvel Comics.
I can see the significant lack of X-characters detracting from that point, but hey, if sacrificing another couple of Wolverines for the sake of Squadron Supreme I'm alright with that.
