I'm currently reading X-Factor (Havok, Polaris, Multiple Man, Strong Guy, and Wolfsbane) and just read #84. It is Part 2 of X-Cutioner's Song. I'm assuming that it is a crossover story.
Should I spend the money on buying the X-Cutioner's Song? Is it a good read? Is it a pivotal event in Marvel/X-Men history? How many Parts are there to it?
Or should I just continue to read through X-Factor without worrying about X-Cutioner's Song?
Thanks fellas!
