"Kid Flash Lost" could mean that we either cannot find Kid Flash or that he is, simply put, not a winner. Neither statement is true in this book, as Kid Flash wins in his quest to help the Flash and the entire time, Bart Allen is right here in this book. Not so lost.
The general point and plot of this title was not lost, either. Bart Allen has been an anomaly for over fifteen years now, and a streamlining of any universe needs to remove anomalies.
Sterling Gates may not have set out to tell what could be deemed "The Last Kid Flash Story," but he gave us a story that is just that: the last time Kid Flash (or any Flash other than the slightest possibility of Barry Allen doing so) would appear in the DC Universe prior to the reboot. Naturally, this issue has a final page send off of "To be concluded in 'Flashpoint' #5." That doesn't preclude Gates from delivering a story that is powered by emotion, even if the emotion doesn't shine through completely.
The art on this book is a mess, but in this case, it works. Oliver Nome and Scott Kolins have very distinct styles and, thankfully, neither tries to ape the other. The story has some kind transitions that play nicely with the art shift, which helps layer in the complete "Flashpoint" story for those readers who were only getting this slice of the "Flashpoint" pie.
Taken as a whole or as a single issue in the flash flood of books in DC's summer event, this book is not one of the best "Flashpoint" tie-ins, but I'm willing to bet it will eventually be one of the "most critical" tie-ins. Of course, I could be proven wrong next week if Geoff Johns boils down the critical highlights of this issue into a smattering of panels in "Flashpoint" #5. All the same, this issue does serve as a nice epilogue to the legacy of the Flash that has served as the spine of the DC Universe since "Crisis on Infinite Earths."
