If your considering buying this book, you have probably read it's prequel already. And if you have, you probably understand why this might be the most hotly anticipated wrestling book in modern memory. Expectations for Undisputed were high.
I have only read it once (so far) but it does not disappoint. Jericho has proved himself as an established writer, who knows his fanbase. The same in-jokes return from A Lion's Tale, as well as a whole bunch of new ones. Remember the Jericho curse? It's back, with a vengeance.
Undisputed also spends a lot more time looking at some of Chris' non-wrestling work, especially Fozzy. Fans of the band will definitely enjoy it, but so will people that are interested in the music business in general. It's an eye opener for anyone that didn't previously think record companies were slightly evil. But it's also testament to Chris' hard work and determination to make the band succeed.
The book also covers Chris Benoit, with more humanity than any account I have read before. It was well known tht Benoit & Jericho were close friends, and for once it doesn't seem like someone is trying to cash in on the dark event for personal gain. With both Benoit and Eddy I was in tears reading, it was incredibly moving.
In comparison, does it live up to all the hype? Maybe. After one highly enjoyable read, its a little hard to tell. A Lion's Tale is one of my all time favourite books period, I have read it at least 20 times. I think Undisputed is a brilliant book in its own right, and strongly recommend it to all wrestling and non-wrestling fans.
