Reading through this entire thread, I've come to realize part of the reason the OT is so much better than the PT: The quotes. Compare:
Qui Gon Jin in Episode I wrote:Without the midi-chlorians life could not exist, and we would have no knowledge of the Force. They continually speak to us, telling us the will of the Force.
Obi Wan Kenobi in Episode IV wrote:The Force is what gives a Jedi his power. It's an energy field created by all living things. It surrounds us and penetrates us. It binds the galaxy together.
Both quotes explained to different generations what "The Force" is, but, to me, the original explanation from Obi Wan is clearly the superior one.
Episode III wrote:Vader: Where is Padme? Is she safe, is she all right?
Palpatine: I'm afraid she died. ... it seems in your anger, you killed her.
Vader: I couldn't have! She was alive! I felt her! She was alive! It's impossible!
Episode V wrote:Vader: No. I am your father.
Luke: No. No. That's not true! That's impossible!
Vader: Search your feelings. You know it to be true.
Both scenes are meant to be dramatic, emotional scenes, yet the only one that ever felt like it had real emotion, real dramatical urgency, to me, was the scene from Episode V. The scene from Episode III, by comparison, just feels like a farce.
Look at the "comedic relief" in each movie:
Episode II wrote:Obi Wan: She seems to be on top of things. (Referring to the fact that Padme had climbed atop the pillar she was chained to.)
C-3PO: This is such a drag. (Referring to the fact that he was being dragged along by R2.)
Original Trilogy wrote:Han: Look, your worshipfulness...
Leia: Will somebody get this big walking carpet out of my way?
Leia: Why, you stuck up, half-witted, scruffy-looking... nerf-herder!
Those two lines from Episode II made me groan out loud when I heard them in the theatre due to their lameness. I was like, "Really Lucas? You had 2 decades to come up with a script and this was the best you could do?" Those lines from the OT (among others), were much more humorous. Using light-hearted banter/sarcastic remarks really helped build the camaraderie amongst the characters as opposed to just making lame puns about the situation.
Heck, even the "Apology Accepted" scene with Vader succeeded in giving this villain a (admittedly dark) sense of humor and humanizing him.
Anyways, I could go on and on, but I'll stop here. For those of you who don't see my point yet, I'll hand it off to Yoda:
