Watched the ROTK (thanks to a generous reader) special edition this weekend. Unlike the first two, for which I thought the extended version were better more complete movies, for the ROTK I thought the extra scenes, taken as a whole, made it into a worse movie. That's not to say all extra scenes were bad, or that they weren't fun to see, but the neat thing about the first two was that the additional footage really made them into better movies. For for the ROTK, they were (mostly) just "fun extras."
