The good news is this movie tested very well.
The bad news is the test audience was entirely mindless growling zombies.

A few rows in front of me were a group of teen aged boys (supposedly the target audience) and they listlessly took in the length of the movie before unhappily shuffling out of the theatre.
People Who Make Movies: Listen to me. Zombie movies are not hard.
There are really only three ingredients you need
1) a shotgun
2) a heroic character who unfortunately gets bit and dutifully sacrifices him or herself
3) a bunch of snarling flesh eating zombies.

This movie that these three ingredients (but barely) and didn’t mind to include anything else of any worth whatsoever. One also must wonder where the title comes from. Does anyone know what ‘extinction’ means?
Alternate titles I would offer would be:
Resident Evil-Barely Attention Gathering Even If Stoned
Resident Evil-Kinda Like Every Other Movie That You Hate
Resident Evil-Better Than Watching Women’s Golf

Milla Jovovich is an angel who in this movie just looks like she’s fallen from grace and must reside in a sophmoric, coked out writer’s second draft. Milla, I love you and I have a script written just for you. It involves a shotgun, a heroic bitten character, and a bunch of zombies. I wrote it in a half hour over a six pack of Newcastle, and I guarantee it will be 8 times better than ‘Extinction’.

Maybe the movie was effective to some degree.
It did make me want to eat the eyeballs out of my head.

Final Word: Resident Evil Extinction is to movies
what the pinky finger is to ‘the shocker’.
