- Designated Hero: It can be hard to root for the protagonists of this movie.
- Matt is both selfish and lacking in empathy for how the stress of her job has made G-Girl the neurotic mess she is.
- G-girl using her powers to get back at Matt in turn makes her come off as a controlling and abusive stalker.
- Designated Villain: Bedlam, before he makes a HeelFace Turn at the end. He is stated to be a Super Villain and G-Girl's Arch-Enemy, but despite this we never see him commit any crime nor fight G-Girl for most of the movie. His only "villainous" acts were to de-power G-Girl, who by this point has been established as a terrible superhero and a Psycho Ex-Girlfriend, along with hanging Matt from the Statue of Liberty (though he knew she'd save him easily).
- Draco in Leather Pants: See Designated Hero above and Unintentionally Unsympathetic below.
- Foe Yay: G-Girl and her archnemesis, Professor Bedlam. They end up as a couple when Matt convinces Bedlam to confess that he's in love with G-Girl. Interesting, considering the aforementioned Superman-Lex Luthor parallel...
- Misaimed Fandom: Some women see G-Girl as a character to look up to.
- Rooting for the Empire: Those who root for G-Girl to come out on top in the end instead of Hannah.
- Unintentionally Unsympathetic: This is due to the fact Matt breaks G-Girl's heart and doesn't show much concern about the fact depowering her will probably result in many innocent people being killed. His lack of concern about her and treating their relationship as It's All About Me also hurts any chance of us taking his complaints seriously. There is also the fact he casually dumps Uma Thurman as Supergirl so many audience members were confused, even if she is a neurotic mess.
