Jack Sawyer is still an uninteresting character. The ending was abrupt and unsatisfying. The darkness and horror elements, like children in slavery for the greatest evil in the universe, felt forced—as if someone had tried to think the worst thing they could come up with and go with that. I didn't enjoy the Dark Tower series very much so I wasn't thrilled for the crossover either.

There were some good details too, like Henry; he was an alright character.
