The title says it all, really.
I'm not a big superhero comics fan but MAN am I pissed off at Catwoman's new direction with DC's big ugly publicity stunt; though this strip is less directly about that and more inspired by general frustrations I've had for a while of which that was a particularly prickly straw.
Also, I recognize a character can be busty and still legit/used for purposes other than titillation (not the best example but the only one coming to mind at the moment: the Hernandez Bros' Luba) but I still went for the "LOL CHEST" joke since it was easy to do and this strip is nothing if not lazy.
Wordy author comment today I know. In addition to the fine author mentioned in the alt text, this lovely article from ComicsAlliance is also worth a good read if you're as sick of this bullshit as me: http://www.comicsalliance.com/2011/09/22/starfire-catwoman-sex-superheroine/
