Half a star.
This is a hideously curated collection of bits-and-pieces from Marvel's MAD rip-off, Crazy. I have fond memories of Crazy from around age 10, including some hilarious parodies that I didn't expect to be included here, since they would surely piss off people in today's PC climate. But could they have chosen ANYTHING funny for inclusion in this collection, especially since, barring an omnibus geared towards nostalgic collectors with too much disposable income, this is all of the classic Crazy that we're ever likely to get..? A huge chunk of this volume is taken up by 2019's Crazy one-shot and a reprint of 1983's OBNOXIO THE CLOWN VS. THE X-MEN (It wasn't especially funny in 1983, and it hasn't gotten better with age.), there are a handful of Crazy covers (Nicely done, but...unnecessary here.), a LOOONG, unfunny tutorial on how to create your own Marvel comic, some horrendously unfunny Marvel singalongs, and close to ONE HUNDRED PAGES of Teen Hulk. Really. One PAGE of Teen Hulk is all that you need to see that it isn't funny. Editor Jennifer Grunwald must have the worst sense of humor ever to think that anyone would need this dreck to be presented in what I assume is its entirety. And...is this really the place to collect "Marvel Meow" variant covers...? They could have included a few Dirk McGirk strips on those pages!
To be sure, there are a few funny bits in this collection. The new issue of Crazy is better than I expected it would be, some of the old Lee/Kirby/Ditko comics get redialogued and generate a few laughs, and the rejected Marvel comic characters are the highlight of the book. But overall, this is just a wasted opportunity. I can't imagine any new readers would pick this up and want another volume, and older readers will just shake their head and wonder who the hell chose these contents.
