Cowboys & aliens - 2011

Well, it's one of those things that I actually enjoyed this first time, but see no need to watch it again. It's a good enough film, considering that the title was not reassuring, so I expected much worse. In a few words, this is like a classic western movie, only the enemy is what you usually find in sci-fi movies, not in westerns: Aliens, bad bad aliens.
Jake (Daniel Craig) is a robber, and when he brought home a sack full of gold coins he attracted some unwanted attentions. A 'ship' of aliens is here to steal all the gold they can find, and they abduct humans to study them, to find their weaknesses. Jake watches them killing his woman, but when it's his turn, he's able to free himself and somehow he manages to escape.
He wakes up with total amnesia, and with a metal thing on his wrist that he can't take off.
Meanwhile in town there's a typical western situation going on: the arrogant kid of the local rich man goes too far and is arrested, and his dad the colonel comes to demand his release.
When the village is attacked by the aliens, and many people are taken, Jake discovers that his 'bracelet' is a powerful weapon. To get back the people abducted, Jake goes with the old Colonel (Harrison Ford), doc (Sam Rockwell) and the sheriff's young grandson, because the sheriff (Keith Carradine), the kid and doc's white have been taken with many others. Someone else joins the expedition: Ella (Olivia Wilde), a woman that seems to know a lot about Jake. When she's taken too, Jake does his best to save her, and just when he thought he had succeeded she is severely wounded and dies.
They're captured by indians, and they burn Ella's body. A few moments and a big light breaks out from the fire, and a naked Ella, safe and sound, comes forward. She explains that she's 'not from here', that she took this form to talk to people but had no idea of what this body could take. She explains them all about those gold-hunting-aliens, saying she came here to stop them. Finally, remembering how he escaped, Jake takes them all to the ship, and with the help of his old band of criminals as well as the indians, all together they attack it.  Jake and Ella free the prisoners, then she stays there to sacrifice her life in order to destroy them, and avoid them coming back with help.
At the end he goes away , alone.
I'm grateful that Percy was among the abducted because I really couldn't stand him; glad that doc's wife made it, now he'll finally appreciate what he has; the aliens looked like ugly monsters, which is the rightful look for the evil enemy; I liked a lot when Jake carried Ella's body all the way, never stopping to check if she was alive, not accepting the idea that she could not be, even when they all told him it was too late.
For sure it is absurd and stupid that a race so much more advanced should be defeated by cowboys, that they would fight with no weapons whatsoever, when we clearly know they have weapons, like the one Jake stole from them, so they had Ella explain to us that the aliens will be unprepared because they think of humans as insects, merely a nuisance, and will not expect a fight. Still, after hearing Jake use his weapon to kill them, none of aliens got one.. did Jake take the only weapon on the whole ship? Ridiculous. Anyway, aside from lack of anything reasonable, which was not a disappointment because I wasn't expecting any after seeing the title, it was a nice movie to watch, good action and some classic western scenes.
Glad I watched it.
Once.
I think that's enough.
