Not sure if the site reviewer watched this all the way through -- While there is little to no nudity, there is alot more sex than the Commonsense review presents. The "couple making out" is a mostly clothed couple having sex (while speaking lines of dialog), and the foreplay continues (woman moaning) while the man talks to the interrupter. Really a disturbing scene.
Also, what CSM calls "some drinking among party goers" is a serious understatement. Every surface in the kitchen is covered with bottles and glasses of alcohol, and most of the characters are drinking and drunk most of the time, either lining up shots, drinking from hip flasks, etc.
I enjoyed the different take on Shakespeare, but I would not take young teens, unfortunately,.
