Must-see, great, classic, yadda yadda

Rating: 10/10 (20 December 2001)

I can't improve on the heaps of praise for this film, one of my favorites ever, so I have to ask questions.
1)During the meeting of some of the top-brass aboard the Death Star, a skeptical minion questions Vader's Jedi powers and the lack of re-acquiring the stolen data tapes. Vader's response was to choke his critic and utter a strange rebuttal. "The Death Star is insignificant next to the power of the Force". Excuse me, but can't the Death Star blow up planets ? And what does Lord Vader use the Force for ? To choke insubordinate officers who question him ! During the whole Star Wars filmography, the Force is used to: cloud men's minds, to choke and physically hurt others, to levitate people and objects, sense other Force-users, etc... Vader can't blow up planets or even come close to it.
2)When the Death Star arrives in the Yavin system, they wait until the moon with the rebel base appears in the targeting cross-hairs. This of course, helps the rebel pilots organize , attack and defeat the Death Star. So I ask : Why didn't the Death Star blow up the big planet in front of the moon upon which the rebel base sits ? Then they would not have had to wait until the orbit was aligned properly. Perhaps I can answer my own question.
Maybe the Death Star needs to recharge the old batteries after a big hit. Of course, they have no problems hitting multiple targets in 'Return of the Jedi'.
