If you've seen Day Of The Dead, you've basically seen Resident Evil: Extinction

Rating: 4/10 (1 October 2007)

First, a warning. This is extremely filled with spoilers. I checked the box but there is a lot of spoilers. Just wanted to give you that preference first.
I had really high hopes for this film but from beginning to end, it just left me utterly disappointed. If you're expecting much from this, readjust your radar or else you'll be disappointed like I was.
My biggest gripe was this was just another zombie movie. Truly it was that. There wasn't much intrigue, not a lot of suspense, it wasn't even really all that action-horror that the other two had. It was simply... Resident Evil characters layered of the plot of George Romero's Day Of The Dead. Let me summarize why this is for you: 1. A group of scientists and the military hide in a bunker underground as the world is over run by zombies. In RE:E, Umbrella is hiding in underground bunkers throughout the world as it is being over run by zombies.
2. The scientists are trying to domesticate the zombies. In RE:E, Dr. Issacs is trying to domesticate the zombies.
3. Domestication goes badly and Bub the zombie turns on his "trainers" shooting them with a gun. In RE:E, Dr. Issacs is bitten by one of the super zombies he creates with blood from Alice's clones.
4. The group of "heroes" takes a helicopter and escapes to a remote island where there was no chance of the infection spreading. In RE:E, Claire and the remaining members of her convoy escape via Umbrella helicopter to Alaska where radio transmissions state there is no infection, and that people are living happy lives outside.
There could be more, but this is just me going on what I definitely saw.
This movie wasn't enough of a Resident Evil movie and became much more of a typical zombie movie. We had your stereotypical guy gets bite by the zombie and hides it only to turn at a critical time (LJ), someone holds back a group of zombies to save others (Nurse Betty), and the guy bitten by zombies who forfeits his life to save others (Carlos). All of these were played out in all the other zombie movies we've seen. And it's especially unfortunate that Carlos is fate is so stereotypical. The actual event was decent but it still boiled down the same old plot device.
And then let's talk about plot holes for a second. There is no explanation of what happened to Jill Valentine or Angie Ashford. Oh and as for why Alice separated from the group and was by herself for the part of the movie, that was covered in like a minute conversation between her and Carlos. And they barely explain Alice's new found powers and why she suddenly has psionic powers.
And character development. Really, and truly, this was sad. Claire Redfield is brushed over. She runs a convoy of survivors, looks for ways to survive, but they don't really do a lot on her background. K-Mart, who is Claire's "baby sister" in a way, has a brief conversation with Alice simply covering the fact that she was found at a K-Mart and everyone she knows is dead. Not a lot more then that. I would have cared more if they had developed these characters better.
The best character development was that of Dr. Issacs and Albert Wesker, even if Wesker only appears via hologram from the Umbrella facility in Tokyo. Wesker's evilness is portrayed well in the brief scenes we see him in and Issacs is shown to be a true son of a bitch which makes you definitely enjoy it when he comes to his demise.
I will say this on the positive. The actual action sequences were very good and still hold true to those of the previous ones and definitely seem like something you could see in the games. This was a nice touch. Alice vs Tyrant, convoy versus seemingly never-ending box of zombies, and even the infected crow battle were definitely things you'd expect to see in the game.
Unfortunately the ending left me a little sour. Let's just say they leave it open for a fourth, but you probably won't want to see it by the time you get done. Let's just say it appears every facility has a Queen and Alice makes nicey nicey with the White Queen in this one. Oh yeah, and we never actually do see if Claire's group actually makes it to Alaska... guess that could be another tie-in for the next one.... if they make a next one.
It gets a 4 for the action spots and showing how truly evil Dr. Issacs is, but everything else came in sub-par. Doesn't seem like Anderson really tried like he had in the first two movies. Just a shame. If there's a fourth one, I hope it redeems some of the badness of the third.
Bottom line rating, a good time-killer, go see it with friends and have fun movie. But if you're looking for something that takes the Resident Evil franchise in the next direction, don't look here. Go play the next game when it launches, that will move the franchise. This unfortunately took it a step back.
