Crisis on Infinite Earths
Crisis on Infinite Earths was written by Marv Wolfman and illustrated by George Pérez and is still one of the most interesting stories ever written. It features so many different heroes and a truly epic battle. The destruction of all life in every single universe is not that common after all (not even in comic books). The artwork might not keep up to modern standards, but that is not important in my opinion. For the time it was very good and also pretty detailed. It is also remarkable, if you realize how many different characters the artist had to include in his panels and he got them all spot on. With its over three hundred and fifty page, you will stay entertained for more than just a few hours. It is one of those stories that every comic book fan should have read.
