Community theater gets a bad rap. The moniker brings to mind mediocre actors, ramshackle sets and costumes pilfered from the racks of the local Goodwill. The people in the audience only show up because their cousin plays Villager 1 or their little sister is working the lights. If those are your expectations walking into Two Harbors High School for a performance of “Fiddler on the Roof,” prepare to be proven wrong. The Lake Superior Community Theater production has its flaws, of course.
