You’re being downvoted because of the subreddit you’re in, but you’re tasing valid questions. While valid, they’re often times regarded in the writing and editing rooms as “creative discretion.” Meaning yeah they could show all that stuff but is it the best use of time? Could they use that time to better the exposition instead? Can the viewer be trusted with not being shown every little thing? Of course the viewer can... but the execution is what leaves the viewer asking these questions after watching or not. Maybe it wasn’t executed properly for your tastes, and that’s absolutely fine, because your questions are completely valid
