I always thought the EE of "Fellowship of the Ring" had the most to offer; the biggest thing we really got out of the EE of "Two Towers" were Faramir's flashbacks, and I personally think those flashbacks should have been in the theatrical versions, as they would have helped to show why Faramir's in a bad mood when he encounters Frodo & co (Eowyn's stew scene should have been burned and barred from ever being released anywhere). The EE of "Return of the King" seemed better than TTT but still didn't measure up to FOTR in terms of bonus scenery. I must say though it was nice to finally see Saruman's death (I will never forgive Peter Jackson for not including it in the theatrical edition), and I enjoyed the extra scenes of Faramir's problems with his dad and more Eowyn footage in general (I dig Miranda Otto). I even enjoyed the Legolas/Gimli drinking game, even though it wasn't necessary to the film in any way, shape or form, though it did succeed in doing something all the scenes of Gimli falling off his horse or in some way making an foolish ass of himself failed to do - it made me laugh.

JRR Tolkien once said that of all the characters in his LOTR books, the one who came out being the most like himself was Faramir. I have a feeling that Mr. Tolkien would not have liked the way Faramir was depicted in the theatrical cuts.
