A perfect sequel (spoilers)

Rating: Null/10 (30 March 2008)

Thank the cinematic gods for pluralisation. 'Oh, what's that? Alien only had one critter? Well, let's slap an 's' on the end of the title and have hundreds of the bastards. It'll be great.' And indeed it is.
Die-hard fans of Alien may bemoan the different approach that Cameron takes  lots of guns and the Aliens themselves reduced to bugs to be blown to pieces  but the film is true to Scott's original while taking it in a new direction. It's a perfect sequel. The fidelity to the original includes the creepy atmosphere and the slow build-up, but this film has more action and more of an emotional pull. Indeed, it's the relationship between Ripley and Newt that elevates it to something more than just an excellent action film.
The final act, which sees Ripley head off alone into the Alien nest in order to rescue what has become her surrogate daughter, has a whiff of absurdity to it. Skinny woman with a massive gun and flamethrower attached to her and she's going to kick butt? Yeah, right. But because Weaver and Cameron play it so straight, and because you've become so attached to the characters over the course of the film, it seems like the only thing that could happen. You totally believe in Ripley. This is something she just has to do.
And it helps that there are no attempts to indulge in empty grandstanding. This is just a simple case of a mother going into hell to rescue her daughter. And as everyone knows, there's nothing in the world you should fear more than a woman who's trying to get her child back. Mothers are tougher than any Alien Queen, a point illustrated by the fabulous moment when Ripley burns the Alien Queen's eggs.
However, the bond between Ripley and Newt was less explicit in the original cut. But in the Special Edition we get a great scene where we find out, because she spent so much time drifting through space in hypersleep after surviving the Nostromo, that Ripley's real child has died as an old woman. It's a great little scene and gives more depth to the relationship between Ripley and Newt. I'm kind of baffled as to why it was cut out.
However, other stuff in the Special Edition doesn't fare quite as well. The least successful inclusion is the scene on the colony where we see Newt's parents find the derelict alien ship from the first film. It's kind of pointless and it's not particularly well filmed or acted  I can easily see why it was cut out. And plus, part of the joy of Aliens was not knowing exactly what happened on the colony. It was creepier when we could try and imagine it ourselves.
I'm also not a huge fan of the sentry gun sequences. Most people tend to love them, thinking they add to the tension. But to me they only seem to highlight the budgetary restrictions. You seem to see the same bit of footage of an Alien exploding over and over again. Plus, for me, there was greater tension when you saw less of the Aliens. The longer you have to wait for the attack, the bigger the pay-off because you've been wound up that little bit more.
But although the big attack where the Aliens come crashing through the ceiling is magnificent, I prefer the first encounter; the one where the cocky Marines are slaughtered in the hive. What makes the scene so fantastic is the way Cameron uses the Marines' cameras, the ones they have strapped to them, to add to the confusion of the attack. It makes it even more visceral - we see a lot of the action take place on a series of monitors.
But this use of monitor footage also serves as a nod to Alien. When Dallas and his crew head off to the derelict ship this technique is used to build tension. But Aliens takes the concept that little bit further. And it's this unseen enemy, and the Marines' cockiness, that makes it feel like a Vietnam War film. The Marines start off with complete confidence and then are gradually broken down by an enemy that is less well equipped but that can adapt to its environment better.
However, going back to the way that Cameron builds upon the ideas that were started in Alien, I love the use of Bishop in the film. After Ash in the first film, we maybe expect another unhinged robot or at very least a company stooge. And at the beginning Ripley treats him like crap. But after hinting that he might be another android psycho, he turns out to be heroic. And it's a lovely moment when Ripley finally tells Bishop that he did well. In a film that is relentlessly violent, it's nice to have a moment that has such warmth.
Aside from building on the concepts started in the first film, another one of Cameron's strengths is creating memorable characters. No one gets lost in the mix. All the grunts stand out. My personal favourite is Hudson, the whinging scaredy cat who eventually grows a massive set of balls and kicks some serious Alien butt before being killed. Every line he utters is a work of genius. Then there's Vasquez. I don't know what it is about Cameron, but he always seems to be able to create believably tough female characters. Therefore it doesn't ring untrue when she kicks an Alien in the head and shoots it in the face. You believe this woman is capable of doing this.
But smaller characters stand out as well. Drake and the Sergeant are great in what limited time they have, and I love Gorman, the poindexter turned good. And then there's Burke, who proves that a greedy company man will always be worse than an acid-drooling monster.
