I think the arguement there can be made that the crew of the Nostromo are simple truckers and the crew of the Prometheus are trained scientists. Alien was also a way more focused experience while Prometheus just kind of flops around on the floor at an attempt to find its feet. Because of this the mistakes it makes stand out even more prominent.the December King said:I should probably state that I liked Alien better than Prometheus up front, before I continue. It's just a better story. Nonetheless...
1)in Alien, the fact that they were wandering around like that in the first place was careless anyways, especially seeing as how they struggled to move about in those suits. Not a good getup for spelunking, at any rate. Besides, he did in fact walk over to the pulsing egg thing after he fell, and, well, actually shoved his face into a creepy WTF thing, right? And 2), while the quarantine / emotional debacle was way better than a robot infecting someone with a WMD, it still doesn't change the fact that a rather obvious and critical mistake was made. However 3), in Alien, yes, they never removed their helmets in a silly place... I guess there is no real parallel with Alien to Prometheus on this count, because the bulk of Alien takes place in the Nostromo, not the Engineer craft. So... point conceded.
I just think that people are wearing blinders if they think that stupid mistakes don't happen in the 'classics'- stupid decisions are a staple of horror. Was this one harder to believe than most? Maybe. But I still enjoyed it.
Now I kind of like Prometheus, but when you think about it it's a really superfluous movie. Everything it tries to do has been done better by Alien, right down to the android subplot.
