I agree, I was looking at it just thinking "how the fuck will artificial gravity work on that weaving thing?!" and "Would they do a Total Recall thing when going from 'ring to ring'?" I loved it.
Sadly I didn't think the same of the rest of the film. I needed a piss before the moment the 'weapon' was tested [came back just at the end so was slightly confused]
Either way, this was the worst film in the trilogy for me. The first set it up, the second gave it that dark edge (I've not seen Wrath of Khan) but this seemed to do nothing. The swarm of ships was amazing but little was explained as Krall's gaining of such a fleet (I think he said that "I fapped with the inhabitants of this planet") but apart from that much was left unexplained. He must've known of the condition of his ship but decided not to do anything with it, it obviously wasn't invisible all that time.
But what really didn't do it for me was Krall's motivation. Bana wanted to restore his planet/fuck over Vulcan because 'they destroyed his planet'. Khan wanted to save his crew/Robocop wanted power for war. Krall just wanted to fuck things over for the sake of fucking things over, whining like a little bitch about being abandoned for 100 years. Let it go you pussy.
