I bought a blue ray reader writer drive for my PC. I learned that apparently a PC blu ray drive cannot play movies. I own the drive, i own the disc, why can't I watch my movie? Because every customer is legally obligated to help protect the film industry's bottom line?

It can play movies. You need software that supports playback. This is true of DVD too although for awhile MS bundled one with Windows and Apple with Mac OS X. These days MS doesn't and you need to download one separately. A program like PowerDVD or WinDVD will let you play both.
