I believe the cable car scene was more likely rear projection than blue screen. < /nitpicking >Spencer Draper said:What are bad are the bluescreen shots in the cable car fight and boat chase.
The movie has some really terrific sets and production design, I'll give it that.I've always found the shuttle flight and space station quite effective despite obviously not being up to 2001 or Star Wars standard. The budget costs are shown on-screen with the very lavish look of the film.
