Chosen answer: Because he's an idiot. From the story point of view, they needed the vault to actually be physically open so that the release of the virus would be a credible threat. Unfortunately, this required that Peter conveniently forget that he could simply walk through The Wall and use his telekinesis to tear the door open instead. Peter's increasingly large arsenal of abilities, where he ended up having pretty much any ability required for any situation, led to a situation where it became necessary to either have Peter apparently forget that he had a given power, as with the vault door scene, or become naively trusting, as with his refusal to scan Adam's mind to confirm his good intent. This problem, which simply made Peter look increasingly dumb as the show progressed, may well have been a key factor in the decision to severely reduce his ability during season three.

Chosen answer: No, it's not, but not every gun shop owner is reputable or responsible.

Chosen answer: In response to your first part, its simply a case that Vader missed the opening, he clearly has no issues with striking down someone unarmed as he demonstrates later. In response to your second question, its a fault with the effects used at the time that when the lightsabers were held at certain angles, the effects used to 'paint' on the shimmer of the lightsabers couldn't be applied because there wasn't enough of the required colouring.

Chosen answer: Randall is telling him that the ending of the film would have been better if Frodo and Sam had had gay sex. This image grossed the guy out to the point he puked.

Chosen answer: The German's powers could be limited in ways of heaviness of the metal he is manipulating. Meaning the door could be too heavy for him to rip off.
