I'm reading this as part of my read-through of all X-Men comics because this iteration of The Avengers features Beast fairly prominently. In fact, this is the first book I've read in my chronology where Beast is dropping "Oh my stars and garters!?" almost every issue.

If I were recommending completist, necessary, casual, or just iconic read-throughs of the X-books, I would skip this.

It's a perfectly fun Avengers books with a constantly shifting team of heroes, shifting teams of writers and artists, tons of continuity cameos, and even The Avengers first throwdown with Thanos at the end, but it really doesn't add anything to Beast's story, he's just a prominently featured background character being heroic but not getting any character development. We do also have The Scarlet Witch and Namor have some moments in this book, but none of those moments are particularly epic, either.

Should you read this if you want a good Avengers story? Absolutely. A Beast/X-Men story? Skip it.
