I finally had the time to watch this extended version that I bought four and a half years ago. I watched the first one, the second one, and when I went to watch the third one the disc is missing. Since it's been so long I am screwed. Thank you quality control. I am unhappy about this to say the least.
I guess my only recourse is to buy the third movie separately. I hope I can get the same extended version because I'm not buying a whole other trilogy just for the third movie.
So the lesson here is to open your product as soon as you get it to make sure it actually is the proper product. What a pain in the ass.
