Yep. I think working with themes of hope and humor can often be HARDER to write in a believable way.

Then you have Avengers Assemble and Hawkeye, which embrace the genre while at the same time breaking conventions and writing good character development.

*nods* And it's not like those don't have their moments of sorrow, but they remember the joy of comics that I think some writers forget or try to ignore.
