issue with all Star Wars movies (not a spoiler)

Last week (before anyone saw the new movie, so there are no spoilers):

Me: "I have an issue with all the Star Wars movies.  They always fly through a narrow tunnel and shoot one spot and then explode a gigantic ship.  You'd think the engineers would learn the first time.   It'd be passed down as lore.  'Remember to double-check the design so it can't be exploded from a single point.'"

Others: "True, they exploded the Death Star twice."

Me: "And Anakin exploded a big station in Phantom Menace.  You'd think that would be the failure case that gets repeated in engineering class, like how we all watched that video of the bridge that collapsed."
