Similarly, this is the first Alien film in which the alien doesn’t cast a shadow over the movie even when it is not on-screen. The aliens are missing in action for long spells in Alien Resurrection, and you just don’t feel the danger of their (hidden) presence. There’s no belief that they could be hiding around any corner.
So I champion Alien Resurrection for its decision to, in honor of the series, try something new. But I assess, finally, that “dark comedy” is not the most successful approach for the franchise.
