Is there merit in "A Funny Thing Happened on the Way to the Forum"?

Although the movie contains many offensive and stereotypical references to women the movie still achieves its goal: comedy. Even when it is most offensive it never goes to far; however, it does test its limits during the presentation of the races of the slave women. Nowadays people do take more offense to such pieces but I still feel that the movie is worth showing as it is interesting and funny. I feel this movie should still watch movies like this because they are very telling of the development of film and levels of comedy accepted in society. In any movie you can find offensive material this film is just straight up with it. How do you expect a director to even closely recreate Roman society if they are not true to the conditions of the time?
