If all the characters in Testosterone behave cartoonishly, maybe it’s because the two-dimensional protagonist, Dean (David Sutcliffe), is a graphic novelist. When his stereotype Latin lover, Pablo (Antonio Sabato Jr.), leaves their L.A. home and vanishes, Dean flies to Buenos Aires to track him down. The rest of the film unspools aimlessly as Dean stalks his blurry sketch of a boyfriend (what does he see in him, anyway?), gets stonewalled by imperious materfamilias Sonia Braga (can scenery be Atkins-approved?), and carries on like the proverbial ugly gay American, ranting and waving guns at the locals, all of whom seem to hide some mysterious link to Pablo. We’re teased with the prospect of a deeper context, but hints that Pablo’s family is politically well connected are abandoned as soon as they’re mentioned. At least we’re spared any Evita jokes.As far as we can infer, the only explanation for Dean’s bizarre behavior lies in a possible excess of the titular hormone. In any case, a more accurate title would be Melatonin.
