Theatergoers found a lot of reasons to dislike Paul Tei this season. He played a cold-blooded child killer in New Theatre's Never the Sinner and a hot-blooded serial killer in GableStage's Popcorn. But he is so good at being bad that you can't really hold it against him. Tei is the kind of actor who looks at a role not only as an opportunity to perform but also as an opportunity to create a role. Consequently he can portray several different degenerates, and his performances never overlap. As Wayne, the gun-toting redneck in Popcorn, Tei kept us riveted to our seats -- appalled and laughing. As Richard Loeb, a wealthy young Chicago man who, along with his lover, kills a young boy on a Nietzsche-inspired whim, he was equally appalling. But Tei never let audiences simply dislike his characters. With his willingness to take risks and push the boundaries of character definition, he could make Ted Bundy funny. For example, in Never the Sinner, he dared to play this insolent, arrogant murderer as childlike and capricious -- clubbing a kid in the head one moment and going out for hot dogs the next. Tei's topnotch acting transformed these two good plays into excellent ones.
