Only reading period gives the January theater season much appeal, but there are a few things on his weekend which are good for more than just killing time. Sleuth is wrapping up its Boston run this week, a last chance to see the theatrical original. Only whodunit literati begrudge Anthony Shaffer his many tricks, other find it delightful. One Flew Over The Cuckoo's Nest drew many critics' sneers when it opened off-Broadway. While the dramatization might not so nearly approach the greatness of Ken Kesey's novel, it's powerful enough on its own. Godspell keeps youthquaking along with spirit and a few tunes, if little else.
