I loved it - especially the little flashlights that you twirled around and made the trapeze artists go nuts. For the families at HBS, this ought to be an excellent diversion. From October 8 to the 19th. I like The Druid in Inman Sq. There is also Finnegan's Wake , The Field, Grendle's Den in Harvard Sq.
Movies are a favorite pastime.
We have a 9 screen art theatre around the corner behind 1 Kendall Sq. For rare and older films, you should check out the Brattle Theatre in Harvard Sq. If you prefer Live Theatre then you might check the American Repertory Theatre . And also the Boston Pheonix or improv listings . The play is a prize winner and is expected by all critics to be well done.
