Think the Italian mobster-version of "Beauty and the Beast" gone "Fifty Shades of Grey."
I agree the opening is confusing, and should have been edited (easily trimming 10 to 15mins).
Once it takes OFF (I'm mean literally, their clothes goes flying at the 45-minute point) WOW...Eventually, all the naughtiness does get in the way of the storytelling. Which could have easily been explored with different cultures.
Unfortunately, the Ending didn't give me a sense of something learned or a hidden World adventure explored or feeling even empathy.
Yes, the ADULTS should watch it (get your popcorn ready) to destress your mind for a couple of hours.
PS: If anyone questions my naughtiness; Google "Naughty Tommy books."
