Karohemd's World

Or the first time the fully developed Vader theme/Imperial March came on when Sidious made Anakin his new apprentice.

Yes, Anakin's fall was a longer process but he learned dark side powers like the choke rather quickly. They say the Dark Side is quicker and easier but that was within a couple of days or even less.
That wasn't worded properly in the original post, I admit.

In RotJ, Vader's mask is the helmet (i.e. the top bit with the shield in the back, then there's the face mask that hugs the whole skull and finally there's the breathing apparatus that covers the lower face from the lower lip down.
I just remembered something, in Ep V we see Vader's head from the back in his chamber, just before his helmet is put on and there's no wrap-around bit on the skull, just on the neck. It might well have been a later addition or just Lucas wanting to show off more stuff in ROTJ.

I especially liked the slinging his lightsaber through a droid
That was one of the most impressive Force uses in the whole film as a lightsabre switches off when it leaves the hand, meaning Yoda had to keep it activated by using the Force all the time.
His spinning and chucking of one of the senate seat things was cool, too.

Some of those Jedi were masters. They were in a war situation, all their senses should have been up.

There were very early versions of Tie Fighters and the Star Destroyer, though.
