Run time seems about right since this is presumably setting up the next one.

yeah this one will probably be how all the multiverse is collapsing and then the stuff that breaks apart combines with each other into "Battle World" which is ruled over by Dr. Doom. Second one will probably be the heroes from the various worlds having to remember/find each other again to take out Doom and then establish a single universe that has everyone in it.

The second Secret Wars/Battle World comics I enjoyed. I hope they follow that plot a bit. I will say though with the teasers they've released I already feel that for dedicated Marvel Comics readers they've revealed too much i.e. evil Steve Rogers.
