don't rush
This issue has three stories none are bad the best one has to be the one by J.M.S unless you like silver aged stories if you did your favorite would be the one by Dan Jurgens the art looked great throughout the issue even tough it had three diffrent artist.
THE BAD
None of the stories felt like they were connected and none were that great with the exceptions of the story J.M.S wrote the issue felt off because it went from the present to the past and then the future it might have been better if the stories went from the past to the future.
Overall
this was not a great anniversary issue it felt like it was rushed just to get the book out batman 700 was a better issue you do not need to get this issue unless you are a really big fan of superman.
