Set wise, I liked the 2016 Uniters, the 2015 Protectors, “Force-Ghost” Ekimu, and Umarak the Hunter. Waist articulation was a great addition, and I liked a lot of the new parts (even the excessive translucency, although a lot of sets didn’t use it all that well).
Creatures were a cool concept but most only looked good when joined (the forced requirement of using that new blade mold also hurt them.) I liked the diversity of the Master’s but they all looked too buff and blocky. And aside from Umarak’s hunter form, the villains were all pretty bad.
You should take all that with a grain of salt - because I didn’t buy any. I totally would have if I cared about the story, but there was just nothing about it that grabbed me. I liked the original “Mask Maker” teaser, but that was about it.
Some of the concept art and stuff behind it was really cool, I think the line suffered from a lack of vision.
That doesn’t mean it’s bad to like it, though! Nothing to be ashamed of, if you enjoyed it. Personally? I think it had some redeeming aspects, but there was nothing about it that really kept my interest.
