The excitement of anticipation is always fun, but it's even more fun, (and rare) when the object lives-up to the hype you have created in your head, when it's everything you'd hoped it would be. Such is the case with "Between Riverside and Crazy." This is the show I've been rubbing my hands together for since the Season Announcement. Stephen Adly Guirgis is, in my view, the New David Mamet, because The Old David Mamet went senile. That line will get a giggle out of the Theatre Geeks, but here's what I want the Non-Geek Readers to hear: If you've ever wondered why I go to the theatre, it is because I hope to see a show exactly like this.
