Speaking of Dalek-ineffective guns, don't you sometimes hate it when in movies/series/whatever there's this situation where either good or bad guys are pitted against obviously over-powering enemy, the one that shrugs off both their best troops and strongest weapons... YET said good/bad guys INSIST on using conventional, head-on, fire-everything-you've-got tactics despite all of that?
Can't remember any actual example, but I'm sure someone could come up with something. I mean, it is a standard practice, throwing mooks and filling screen-time with filler, but that doesn't mean it doesn't get tiresome. Sometimes.
Not to excuse sloppy plot progression/universe mechanics, but:
a) When the cards are down and the xenomorphs are slavering on your face, you'd throw rotten tomatoes at the things, if that was the only thing you had with reach... well, unless you're a rip-your-shirt, stand-your-ground, shout-Come-On-Then-You-Motherflipping-Extragalactic-Bioweapon!!!! type of person, in which case you stand there and let it eat/dissolve/vaporise/infect you, probably in order to save some women and children (and corrupt corporate executives) you were escorting, but also (because you'd already proven to be practically the most unkillable veteran soldier, before this) also to evoke the Worf Effect.
b) It's amazing how many invulnerable-to-plasma-weapons enemies, there are in fiction, who have wiped the deckplates with the hi-tech exoskeletal plasma-weapons orbital SWAT-squad, but end up to not have anticipated the need to protect against kinetic 'slug-thrower' weapons.
Item 'b' isn't necessarily
true to any particular situation, but you can bet your bottom dollar that this particular team of SEALIONs (SEa, Air, Land,
Interplanetary and Orbital, Natch) will have seen this kind of movie (as fiction within their
own reality) and revert to the type 'a', above. If it works, they're Dangerously Trope Savvy, and if not then they're dangerously trope-fodder. Either way, often the Force Of Plot is strong.
