An experiment to get an alien out of the blood sample of Ellen Ripley through a clone turns wrong when the alien begins to kill. Ellen must once again decide and save humanity.
This is not a Hollywood space thriller at all, but an intergalactic fantasy driven by the same cheerfully eccentric impulses that have informed a myriad of high-spirited French filmmakers.
[Jeuenet] doesn't push it all the way to "so bad it's good" territory, but he at least gives a healthy dose of the bizarre that makes it memorable, in its fashion.
A lot of fun to watch, and easy to surrender to in the moment.

So campy that it almost plays like a sendup of the series. It is to 'Alien' what 'The Bride of Frankenstein' was to other 1930s Frankenstein movies, and it even shares some of the same themes.

Simply put, Jean-Pierre Jeunet was the absolute wrong choice for this film. His award-winning quirky French visual sensibilities don't mesh well with Joss Whedon's meat-and-potatoes script.
It satisfactorily recycles the great surprises that made the first movie so powerful. And most significantly, it makes a big hoot of the whole business.
