I think FA was probably the best X-over of the 90's, but it's weakest element is kinda that it was line-wide..
The best way to read Fatal Attractions is to read
- The Uncanny X-Men #298 - For The Children! to #304 - Fatal Attractions Part 3: ...For What Have I Done
- X-Men #25 - Fatal Attractions Part 4: Dreams Fade
- and Wolverine #75 - Fatal Attractions Part 5: Nightmares Persist
Reading the build-up to the story in Uncanny X-men gives it a lot more weight, and the other crossover issues aren't really necessary.
