Yes, we also think “50 shades of Grey” was a missed opportunity. A few scenes got off to a very good start, but were eventually a disappointment. You can’t talk about BDSM if you’re not into it. A good thing about it was that it introduced BDSM to the public. A better title, however, would have been “49 shades of vanilla with 1 shade of BDSM”.
Also, you don’t use cable ties & duct tape in professional BDSM play. Furthermore the BDSM-action displayed was, well, mild. His playroom was cool though!
