Query: Infinite Crisis a disappointment

As a young teenager, Crisis on Infinite Earths made a big impression on me. I was a big Wolfman-Perez fan from the New Teen Titans, and was amazed with the effort that went into the Crisis storyline. So I was naturally curious about the Infinite Crisis product. Though I'd always wondered what ever became of Alex Luthor-Lois Lane-Superman-Superboy Prime at the end of Crisis, I quickly realized that Infinite Crisis was a serious mistake and those four characters should have been left alone. The corruption of Superboy Prime and Alex Luthor was not believeable, nor was the duping of the Earth 2 Superman (The Greatest DC Universe hero of all time!) obviously forced in order to make the Infinite Crisis storyline go. So I cannot recommend this weak book.
