On Friday night I rewatched the original, undedited Episode V. SO GOOD!!!
I don't want to compare it to the IVth, because they are both great. But few things I noticed - when Yoda first appears, he looks and behaves like Peter Jackson's Gollum. Lando's role is made to be "deep" enough to not be a cheezy double-crosser. The one thing that I found less good than the rest is the first Luke / Vader battle - there Vader's movements are so overconfident that he looks like a standart James Bond villian for a minute. But I was surprised to see that his "we'll rule the galaxy together" speech was so good and uncheezy. (!) I did not excpect that.
And now for the big secret: in the end R2 fixes the hyperdrive and saves the day falling on top of Chewy. That made me realize something. Remember the Ben/Yoda dialogue "-He is our only hope. / -No, there is another."? Well, I got it! The "another" Jedi Yoda talked about is R2D2 - the first android to use the force. Cause you know he is using the force at all times. He is too damn good!
And now I watch Episode VI! Review coming in a few hours. :)
