I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
In retrospect, this is an important bridge between the two DD series. (One just ended, one just started; this mini-series was published between those two things happening.)
But it feels very much like filler. It's good for bridging, but not all that much more in my opinion. I see what Marvel was trying to do, but I think it was just flat out done fairly poorly.
