Don't really see what's so hard to understand here. The books for most people are living up to the hype that's been building for for few months now. The art is amazing, the dialogue has been enjoyable, and the unfolding of the narrative has been a treat to watch.
Frankly people just seem to be enjoying a quality X-Men story (and future iconic one unfolding in front of them) that Marvel isn't going to walk back in a year or two's time.
