Easy communication and a sharp wit may be the foundations for good improv, but if you want to see what a troupe is really made of, take a look at how they handle a shaky premise. Having watched cast members sustain this Links Hall/Chicagoland Games show while rolling around in Nerf gear to avoid a tyrannosaurus rex made of PVC pipe, I'm pretty sure they've got it. Amiable host Aaron Amendola ushers an audience member through a series of onstage challenges geared toward overcoming a megalomaniac hell-bent on ushering in a dino-apocalypse. The obstacles—which may involve brushing a Wiffle Ball off somebody's shoulder—are too slight to provide any real stakes. It's clear, though, that this crew has the crowd and stage skills to create something special. —Dan Jakes
