The current Silver Surfer is good. It is only quirky and light-hearted once every 3-5 issues. For the most part it is serious. Although, Dawn is quirky all the time.
They met when someone was trying to force the Surfer to do his bidding by kidnapping, via galactic teleportation, the person who was most important to him. (His power was to identify the most important person of the person he was dealing with.)
The Surfer had never met Dawn before, so after the villain was defeated he took her home. Dawn had never left her small town before and wanted to explore the galaxy with Norinn. They have been together for about 3 years now (real time, not comic time).
