The one thing you will learn from My Super Ex-Girlfriend is that even when compared with "breakup sex" and "makeup sex," "superhero sex" is the roughest of all. And, well, that's about all you'll learn. My Super Ex-Girlfriend strives and fails to parody superhero flicks. It's ridden with empty jokes that don't connect, and more importantly, it's just not funny.
The movie opens with a midday jewelry store robbery. This being a superhero movie, the security is expectedly incompetent and we immediately cut to something that moves like the Tasmanian Devil and looks suspiciously like Uma Thurman. It's a superhero named G-Girl.
Next, we meet architect Matt Saunders (Luke Wilson), a prototypical nice guy with a crush on his colleague Hannah (Anna Farris). The one problem is that she dates a model who can't remember Matt, despite meeting him five times. Matt acknowledges he is a "forgettable person," which of course means that the unremarkable Luke Wilson is perfectly cast. Wilson spends the entire film raising his eyebrows and squinting, two activities that are unquestionably hard to accomplish at the same time, but which don't exactly constitute acting.
