The first scene with the dream fight- it was like it was straight out of TOS, except that it was a dream - did they have those in TOS?

Anyway the exciting music, I believe, was EXACTLY the same music from fight scenes in TOS- I think they used an old recording to get that sound.

And of course the set looked like a set, like the old one did, with flat soundstage ground.

I felt like I was having a flashback. When I was a kid in Kansas City in the 1970's, Star Trek was on every evening at 6 pm on Channel 41, and my family sat in front of the TV and had dinner, every day for 3 years- I am sure I saw every episode of TOS 6 times or more back then. That scene really brought me back.
