I'm comfortable that tie-ins fill the void left by the scrimming style of the main Event book, because it's an Event. What do we think the tie-ins are there for? I've always acknowledge that tie-ins are neccesary to the event, and I'm surprised other people haven't recognized this because of past Event dynamics.
What I am feeling flat about in this Event, is that we haven't got a fully formed mystery being imbedded in the story, enough that it makes us come back to see if the next book has more about this something mysterious. All we are being told as an audience is that Ulysses' predictive visions are extremely accurate, so Tony should just shut up and sit down. I would have liked if the Road to Civil War books were pointing to some problem that nobody has recognised yet, but that hasn't been the case. All those RTCW books look like they were a waste of time, and there is no mysterious phenomena going on in the background, and CWII is just some excuse for super heroes to fight super heroes, but that's so boring. We really need some viable premise here to make this Event compelling.
