In Keely Flynn’s chaotic, confusing comedy, the characters from the 1985 film The Goonies reunite as adults to undo a curse that’s turned them into losers. You don’t expect military precision from a zany parody, but if Flynn had established at least a few ground rules, this production by A Reasonable Facsimile Theatre Company might have had more to it than screaming and scurrying around. Watching it is a lot like observing a group of excited people all talk at once about their favorite movie: pretty soon it seems everybody’s taken off on a different topic. –Zac Thompson a Open run: Fri 11 PM, Cornservatory, 4210 N.
