As others have said, this story is a re-write of Damage, which was a well written novel published some decades ago, and later also filmed. I'll be honest, I didn't watch all of Obsession, or rather: fast-forwarded to the end. I wouldn't even mind it being a rip-off if it was well done, but it's not, or not to my taste anyway. The spicier scenes seem to piggy-back on Fifty Shades of Grey, which unlike Damage I'm no fan of, yet even then could've forgiven if done well, but it's all just rather lame and, at least to me, not in the least bit sexy. Lastly, the characters and their interactions feel superficial, with little depth, and if there's any chemistry I'm not feeling it.
