Framed or caged?

Did you ever hear about Nietzsches concept of "Eternal return"?
I came across it in detail the first time today, reading "The Universe vs Alex Woods".
Nietzsche said that there is no afterlife like heaven or hell but that things simply start again from scratch and that you repeat your whole life again and again with no changes from birth to death. In the book it is assumed that he presented the idea to force the reader to

"confront the following question: If true, is this a pleasant idea? Or, put differently:

If you had to relive your life exactly as it was - same successes and failures, same happiness, same miseries, same mixture of comedy and tragedy, would you want to? Was it worth it?"
