Adherence to ‘tradition’ makes the opening a little irksome to me. Jambe Davdar’s reconstruction of the storyboarded opening crawl is something I personally find a lot more interesting; a blue crawl over a snow-covered landscape, altogether different from the first film yet similar enough that an audience would be sure they came to the right film. Not to mention, opening with the launching of the probes removes a bit of the tension and mystery that was in the script; there are two threats, one to Luke and one to the Rebellion.
