When it’s springtime in Chicago the only reasonable question to ask about a play is whether it’s worth the time spent inside. The Rogue Theater production of Nate White’s The Stoic is way too tedious to warrant a “yes.” This tale of dangerously whacked-out, estranged siblings reunited by the death of their father is ungainly and inchoate, often failing to manage the connections and effects it clearly yearns to make. Still, that yearning is a saving grace. White shows ambitions, both psychological and formal, that suggest a talent aborning. Dan Foss’s direction is no help at all, and the casting in the major roles is unfortunate. But the three supporting actors are engaging, especially Dan Waters as a good-natured barfly. Through 5/7: Thu-Sat 8 PM, Sun 3 PM, Stage Left Theatre, 3408 N. Sheffield, 773-509-8140, $12-$15, industry nights Thu.
