On a related note, when I re-watch shows from the 1990's or even early 2000's it's amazing how many problems would be solved with a simple cell phone call or text message. Buffy the Vampire Slayer would be a much shorter show if the gang could just text instead of wondering where the others were or if they knew some key fact.
Can writers plot a story in any given milieu? Yes. Sometimes they do seem lazy.
