True, but like you said, it's done "to some degree" and it's never treated as the main focus of a review. I'm of the opinion that you should only reference the plot as much as you absolutely have to and especially try to avoid the most sensitive spoilers (even if the movie is bad - alluding to plot details through criticism is fine, but spelling them out...not so much). Also, if a movie isn't deep enough for you to have enough to write a review without padding it out with a plot description, maybe you can just not write about it - or at least try to critically analyse the lack of depth and see how much you can write by taking that approach.
As for
Predator, these were just the comments that stood out to me...
The Predator is an alien living in the woodlands of Central America. Why it's sent there or what it wants is never revealed. It's just there and ready to wreak havoc, and from the looks of things like the soldiers skinned alive, it already has.
As far as the first movie is concerned, it's effectively the alien version of a big game hunter who travels across the galaxy looking for new species to hunt, but it also follows a weird code of honour where it won't kill unarmed people (like the squad's female prisoner) and only goes after targets to prove a challenge (like a team of elite commandos).
But they figure if they don't fight it now, it could become a menace to society, and it might not let them leave anyway. So they hold off going to the chopper.
Their reason is survival more than anything else - by the time they stop to fight, it's already killed two of their men so they figure it's better to stand and fight rather than allow it to keep picking them off like they do. The idea of it being a menace to society doesn't figure into it at all.
And there's a few stupid moments, like when they decide to stay and fight the alien in the first place. Maybe the alien was away at the moment, and they could have went the other way to be recovered by the helicopter. They could have taken the chance, possibly gotten to the chopper, and ordered an airstrike on the whole area. Problem solved. But heroes got to be heroic. They got to do everything the hard way. And nearly get themselves killed during the process.
It had already been established that this was their only route to the extraction point so there was no "going the other way" anyway. Besides, it makes more sense to fight an enemy they know can be attacked and killed (and thus confirm the kill in the process) than to keep going and vainly hope that the thing that's killing them just suddenly stops doing it (never mind that an airstrike following a top-secret illegal border-crossing mission on a target that's already hard to find and verify would be much more stupid). I know it's easy to try to nitpick characters' decisions - I've certainly done it a lot in the past - but I figure it's worth thinking hard about why they don't just take the supposedly "easy" way.
As for your recent posts...they just consist of more nitpicks that either have nothing to do with what the movie's truly getting at (as in the fixation on the logistics of
Inception's dream-hijacking technology, which are ultimately not relevant to the story at large) or don't account for human fallibility (such as the main character's shortsightedness in
Rear Window, which reflect how in-over-his-head he gets through his snooping). Again, it's the question of what purpose noticing these things actually serves and how badly it affects the film as a whole - you still thought
Rear Window was good anyway, after all.
