A review by sodope
Superman Reborn by Patrick Gleason, Peter J. Tomasi, Dan Jurgens

3.0

Here we solve the problem with the other Clark Kent, all of these mysterious stuff was set by Mxyzptlk, the may conflict is meh but still not the worst, also we see that "a mysterious man" stills watching Superman's activity.
This book also contains an extra action comics brief arc.
