Biggest problem---they did nothing with PG that truly mattered to the DCU. I'll also note that with the previous post, another PG thread milestone was reached---1500 posts!
That picture though was nice--the artist captures PG in a lighter moment well. I could go with a PG manga series, as long as it was classic PG, and done in not just a jokey style. Some serious stories are kinda needed to balance things out.
Which brings up one of PG's biggest problems over the years---she just never does anything big. To quote Rick Flair, "in order to be the man, you gotta beat the man". PG just never fights and wins against any big time villains in the DCU, and never does the big time feats. They go to Superman and Supergirl---PG is the poor step-sister of the Superman Family---barely ever even acknowledged to be part of it. That needs to change if she's ever to emerge from C or B-list hell.
