Found it to be very enjoyable and of the BIG event arcs of Slott's tenure, probably the best. I also liked almost all of the tie ins I sampled which may just be me enjoying the fan service but they were all fun.
That being said, it wasn't perfect, still think Morlun and his family are boring invincible jerks in period dress (save Karn who I wish had a expanded role). I don't think we got the most mileage out of all the various characters that showed up and as a long time fan of Spider-Girl ('Mayday' Parker that is) even with the ending I feel somewhat cheated by her depiction throughout the event. Another part that I can't really blame anyone for but I think it would have been perfect if they could have tied this closer to Hickman's Incursions/Secret Wars storyline as well and the fact that it doesn't look like they did do it save Spider UK is disappointing.
