As far as I'm concerned, Mattel just does not make quality the highest priority in the way they go about their products. The 4H are the ones who put the majority of the effort into these collectibles because they're true artists. The best decision Mattel ever made was going with these guys, and often when a figure fails to impress it's due to interference coming from the sub-par in-house team. What kind of sucks is that I don't see Mattel improving this brand because they don't seem to be willing to hone down the line to anything meaningful. Pop/NA generally do not go well with MOTU aside from some notable exceptions. Scott's Yankee Doodle philosophy that MOTU's appeal is random grab-bag of wackiness has helped make the brand a huge mess. I know there are plenty of fans who are of the same mind, but it's not one that could ever possibly elevate the franchise into something more appealing or profitable.
Right now, Takara Tomy's MP line is taking up my adult collector re envisioning itch. MOTUC has effectively run out of easy decisions and the slack that Mattel expects the 4H to pick up is just too great at this point. We have a metric ton of figures here, but noticeably inconsistent quality from one month to the other. In the end I feel like it would have been much more worthwhile if Mattel figured out a way to spread out the releases and focus on quality rather than sheer quantity. Then again, there was Voltron.
