All the stories read as an opening chapter to a new series. Whether that's because there are concrete plans to continue, or just an optimistic open ended approach in case the special does well (which seems to be the likely option, and it seems like it's selling well. Yay!), we'll have to wait and see.
Personally, I enjoyed it and I thought the writing and art throughout was of a very high standard. I'd LOVE to see more.
My only niggle is that it wasn't particularly scary (aside from The Sentinels which was genuinely chilling). The focus in most of the stories was on the invincible, seemingly super-human protagonists who I never believed were in any danger. I'd like to see more stories where the monsters and villains have the upper hand and the protagonists are desperately fighting to survive, rather than just effortlessly booting them in the face.
On the whole though, I'd love to Scream/Misty in the newsagent every week/month/quarter/year. Gimme more!
