It's still a month between issues that some are invested in. I liked HOX 1. But have been indifferent to POX 1 - POX 3, which is a month's worth of story. I don't get what's hard to understand about that.
Personally, I am interested in all the present-day X-Men moving forward, but that has not happened since HOX 1. From there to this issue, and most likely next week is a month's worth of issues.
And coming off things like Age of X and Uncanny, some things just feel like a slow burn for fans anxious to finally see the present X-Men in 616 moving forward given the 6 month stall waiting for this series, then the other month stall after HOX 1. Because nothing in-between that & HOX 3 deals with the X-Men.
If you enjoy, great. But people who are a bit annoyed, impatient, or disappointed will always post as well. Everything will not always be 100% positive with no disappointment.
