You know, first thing I said when we got out of the movie theater last night was "I -liked- this movie, and I don't care what anyone says - it was awesome wrapped in awesome fried in awesome." I do agree with the bad points, but this movie was exactly what I needed in terms of series closure (if it is indeed over?)

I wanted to offer perhaps one point of contention to a theory - not to ruin the party or anything, promise. You said perhaps the hanged boy in the beginning is an alternate Will Jr. Jr., but I believe (and I could be wrong, but I'm pretty certain) that the Hanged Boy's eyes were blue, and Will Jr. Jr.'s were brown. Bearing that in mind, the theory can still be toyed with, but it'll need a workaround.
