They didn't have respect for the size of the universe. They made it look small.
I agree with Ebert's criticisms. They were transporting from Saturn to Earth? Or from Delta Vega onto the ship?
And how is it that Spock could see Vulcan from Delta Vega? I also agree that it was convenient how Spock and Scotty both ended up there.
Also, what they were doing for 25 years was hard to fathom. Likewise with the rapid promotions.
And what was the point of firing at the Narada once it was in the grip of the black hole? Why not just turn around and Warp Away right then? How did ejecting the warp core help them escape?
And last, but not least, the first time the Narada encounters a black hole it travels through time. The second time, it falls apart? Huh?
