smart Flash
To me, the Flash besides his rebirth and new series has been defined mostly by his super speed and seems overshadowed by Batman and Superman in both skills, mental abilities, etc.
So this issue was a welcome changed to show Barry Allen using his brain as well as his brawn to outwit his enemies. Yes both seem to have convenient solutions but shows Barry using his wits to reach them.
Plus reading earlier issues and seeing how things have changed over the years provides another amusing layer to the older issues as well for myself.
