I already posted my thoughts over on Eurobricks, but I'll repost them here:
I love the recolored purple version of the Ninjago sword for Krakenskull (or whatever his name is. His helmet is cool too), and the creature in Aaron's set looks absolutely amazing. The Colossus is impressive, and far more solidly built and less gappy than I expected from the prelims. Very nice. Axl's one is interesting, seemingly having a tank portion that can split off of it and some sort of scissor-axe action feature. The castle is kind of messy. Why the wooden, brown doors? The little siege vehicle and pillar/collumn monster are cool, and this is probably the best windscreen parts pack ever. The powers are underwhelming, although I like the robo-Merlok and the inclusion of one of the two squirebots that are actually characters in their own right. The Heligoyle is cool, and the harpy looks pretty nice too. Macy's dragon is underwhelming, and this brings me to a point that kind of bugs me. There are even fewer female characters in this years lineup than last year, and Macy, despite being one of the main characters continuously gets only the smallest vehicles. For crying out loud, the only female characters included in the castle are a pig and a statue. And I'm still kind of confused why every action theme is given a predominantly male cast. It's kind of blatantly sexist, and it makes no sense even from a business point of view. Little boys don't care about the gender of the characters, they care about how destructive the character or their vehicles are, both in terms of play and in-story, and constantly making every lineup predominantly male excludes little girls, which means arbitrarily cutting your profits in half. That last point wouldn't even be a big deal for a series with a mostly male cast if at least some other themes had a mostly female cast to make the fact that a particular theme has a mostly male cast just a coincidence rather than an issue. I can't exactly find the right phrasing, but I mean that the characters just happen to be male rather than that being thought of as the default.
