I couldn't make myself watch episodes 2 and 3. I got 5 minutes into Episode 2 and looked and listened to that wooden acting and horrid dialogue and said "nay nay."
So I'll just discuss some of the technical side instead. Part of the problem is that the whole damn set was a green screen room. There was very little on location shooting and with that in mind you are giving your actors nothing to react to but a frigging tennis ball on a stick. This is amplified when you have a child actor who read his lines like he couldn't act his way out of a paper bag. But even adult actors struggle in a green screen chamber, it gets worse when you get a kid doing it. Did Lucas have a budget for more than two cameras. But much of the talkier scenes seemed to be with a cheap 80s sitcom set up with a camera each focused on one actors head and it switching back and forth. Once you set it, you cannot unsee it. It's fucking terrible. The script needed an edit. Too bad Lucas did not realize that you cannot effectively be your own editor.
So if I was making the movies, I would have done more on location shooting, more practical effects to give my actors something to react to (CGI has it's place but he really did overuse it) and allowed an editor to actually tell me how I was screwing up.
