I usually abhor big comicbook 'events'. They derail the storylines of the books they throw themselves into the path of to the point where you can almost feel the writers gritting their teeth.
Spider-Verse, though, I really enjoyed. For starters, it only involved the Spidey titles, so we didn't have to endure every other Marvel book being forced into the mix. It also tied in nicely with current events in the Avengers titles without feeling the need to actually cross over with them. The threat felt genuine and the stakes were actually really high in a believable way. I didn't feel like any of the characters were safe. It was action-packed, the plot moved forward at a good pace and the protagonists (who, by the very nature of the story, were all quite similar) felt like they had their own voices. There were also a few moments that were genuinely moving. Also, SPIDER-HAM! I feckin' love me some Spider-Ham...
All in all, I loved it. So why not five stars? Well, I had to drop a star because of the parts of the story that just felt like advertisements for the two new Spider-titles, Silk and Spider-Gwen. I find the concept of Spider-Gwen an interesting one within the pages of Spider-Verse, but giving her her own title? I'm not convinced. As for Silk, she couldn't be any more of a Mary Sue character. 'I have all the powers of Spider-Man but BETTER! Great, huh?' No, not great. It's fan-wankery. I wouldn't let a player use this character in an RPG, let alone give it its own title.
These grumbles aside, I enjoyed Spider-Verse a great deal. Now to petition Marvel to give Peter Porker his own book again...
