We just got the Two Towers Extended editon 4 DVD set to go along with the one from the Fellowship. I really reccomend them both. There are a bunch of commentaries on the two DVD's for the movie (with the extended/deleted scenes already in the movie, making it close to 3.5 hours long), and on the two bonus DVD's there are documentary type features on almost anything about Lord of the Rings. I give them both a 10 out of 10.

I'm gonna see it when it comes back to theaters.

lol, I know that this is an ancient topic but I must agree with cobb after having bought the box that contains all three extended editions, they are really good.
