This weekend, movie goers are talking about one movie: “Bridesmaids.”  A new raunchy ensemble comedy, it features a cast that’s almost entirely female. “Bridesmaids” stars Kristen Wiig and Maya Rudolph, of “Saturday Night Live” fame, as well as Ellie Kemper from “The Office” and Wendi McLendon-Covey from “Reno 911.”  Crass to the point of being shocking, some cultural critics are arguing that this could be a watershed moment for women in film and comedy.   Rafer Guzman  is one of those critics. Co-host of the Takeaway’s Movie Date podcast, and film critic for Newsday, he considers the film truly feminist.  But  Kristen Meinzer, co-host of Movie Date, disagrees.
