"Simply put, the What Were They Thinking: Monster Mash-Up Edition is probably one of Boom! Studios's most solid releases to be released this year. As Ron Weasley would have said, it's so ‘bloody wicked' it'll make you laugh so hard you can't even try to figure out what this issue fails to accomplish. The writers have done a great job in preserving these artistic archives while giving them a makeover to reach new heights and most importantly, allow them to see the light of day once again."
