Evolution (2001)

There's a moment in Evolution where you can almost feel the film that could have been. Alien slime crash-lands in the Arizona desert and starts evolving at a ridiculous pace, producing creatures that go from single-cell organisms to multi-limbed monsters in the space of hours. It's a genuinely brilliant conceit. Daft, yes, but brilliantly daft. And for a little while, watching that idea unfold, I was properly on board.

Then it sort of just... doesn't go anywhere with it.

David Duchovny plays a sceptical college professor, Seann William Scott is his bumbling teaching assistant, and Julianne Moore turns up as a government scientist who's more of a liability than a help. The cast is doing the work, I'll give them that. Duchovny in particular leans hard into dry, deadpan sarcasm and it suits him. He's clearly comfortable in that register, and there's a looseness to his performance that keeps things watchable even when the script lets him down. Moore commits to the physical comedy too, which takes guts. But the characters stay thin throughout, more like roles than people, and you never quite invest in any of them the way you need to for the comedy to properly sting.

The obvious comparison point is Ghostbusters: a ragtag group of scientists facing a threat nobody takes seriously, with wisecracks and chaos in equal measure. You can feel that ambition in the DNA of the thing. There's a B-movie heart beating underneath it all, a genuine enthusiasm for the silly premise, and that counts for something. The creature effects hold up reasonably well too. Watching a giant alien evolve into something resembling a prehistoric nightmare in the middle of suburban Arizona is exactly as ridiculous as it sounds, and the film knows it.

The problem is the tone. It can't quite decide what it wants to be. At times it's playing like a straight-faced sci-fi action comedy, then it lurches into broad slapstick, then it nudges at something more satirical about government incompetence and military overreaction. None of those modes are wrong exactly, but they keep bumping into each other rather than blending. Ghostbusters managed to make all of that feel effortless. Here it feels like three different films taking turns at the wheel.

And the ending. Without saying too much, the climax goes big in a way that's more deflating than exciting. The build-up of creatures evolving into increasingly spectacular forms promises a finale that matches the imagination of the setup. What we get instead is a punchline. A film that had been hinting at something genuinely creative settles for a gag and calls it a day.

I kept thinking of the difference between a comedy that commits to its weirdness all the way through and one that loses its nerve at the crucial moment. Something like Anchorman: The Legend of Ron Burgundy (2004) understands that you have to escalate your absurdity, keep pushing it further, trust the bit. Evolution finds a brilliant bit and then sort of stands next to it, occasionally gesturing in its direction.

None of this makes it a bad film. It's perfectly watchable. It moves along at a decent clip, it raises a smile regularly enough, and the core idea is still fun even when the execution wobbles. If you catch it on a lazy Sunday afternoon with your brain firmly in neutral, you'll have a perfectly decent time. I didn't regret watching it. I just kept feeling the ghost of the sharper, stranger film that was lurking just out of reach.

Two and a half stars. A cool idea in comfortable stasis. Entropy, not evolution.
