Grabbed myself Deadwood, Tim Burton 8-film and Tim Burton 3D for just under $80 delivered.
For anyone considering Hobbit and/or Lord of the Rings, keep in mind that there are different versions of the trilogies (theatrical, extended, 3D, 3D extended and what-have-you etc.) so you may need to do your research on which one you want. The one I linked is the theatrical release.
Deadwood can't be the complete series. He didn't end up making the closing movie.
I watched it again last year, and while I enjoyed it, I was surprised by how dated it was, considering how far out it was at the time.
