So, after the decent entertainment of the third movie, the story gets dumber and more nonsensical. This is when the movies really started to go belly up. This is when it became clear that Anderson didn't know where he was going with the film series. All of the potential from the earlier movies is brought to a brick wall where they set things up only to cut them off before the payoff. Where the third movie brought about a clone army, this fourth entry kills them at the very beginning.
Yes, through semi-decent CGI to bring multiple Alices to the screen, we see all of them die off immediately as they try to invade Umbrella Corp. Wesker takes out all of them and then takes away Alice's powers, of which are still poorly defined. Okay, so now she can't use telekinesis or super enhanced agility and accuracy. Throughout the entire film, she is still basically invincible. You'd almost suspect the decision to take away her powers was brought about after the scenes where she uses them were already partially shot.
So, the real problem with this movie, aside from that jarring batch of scenes that basically retconned the earlier films, is that it is a shelter and place movie. Alice pulls off a terribly impossible landing on top of a building. So, instead of going off to find a new community in Alaska, it turns out that it was all some random ship off the coast of a zombie apocalyptic city. Zombies are all around this one building where Alice now finds herself with a whole bunch of refugees that will become entirely superfluous in the long run.
This movie is probably one of the worst examples of horror movie tropes. There's a pervert, a sweet motherly lady who makes sandwiches, a mechanic, the one no one trusts and on and on and on. Every single one of them, aside from Claire Redfield, will be gone and seldom ever mentioned again. They even bring in Chris Redfield, and he's played by the guy from Prison Break. Wentworth Miller literally thought they were kidding when they told him he would be a prisoner who knows a way out of the building. Apparently, they thought the reference by itself was worth putting us through some of the most cookie cutter plot devices as a result.
Even the coolest part of the entire movie is a bit of a downer, as we finally see a cool zombie known as the Executioner. This RE5 zombie makes a small appearance in the movie, and the doublebarreled shotgun Alice uses quarters as buckshot. As unrealistic as this is, it is still somewhat entertaining. I hope you enjoy this scene if you ever watch it, because it's as good as it gets. Beyond this, it's the obvious betrayals, zombie kill jump scares and slowly coming to the realization that MAYBE they should actually listen to the guy who says he knows he has a way out. It is mind-numbing.
Throughout the whole thing, the seemingly unpowered Alice just kicks more ass and solves every problem until she needs to be dumb for the movie to last longer. All of this leads up to getting to the ship off the coast of the city. There's some idiot refugee that betrays the others and steals the plane so he can fly... to the ship and immediately serve Albert Wesker out of nowhere. That's right, Wesker is on the ship and now he wants to literally eat Alice. He says that he is infected with T-Virus powers... like Alice... just go with it--and he needs to take in her essence to regain control because... that's how science works... maybe?
Either way, they fight the video game boss like an actual video game boss and Alice is the only one who exists in Resident Evil Retribution. Nothing is connected and even though Wesker seems like he died at the end of this movie, he didn't. No, his actual death is beyond lame and probably would have been more prominent here. Either way, even with the semi-decent effects and the awesome appearance of the Executioner, this movie is nothing and means nothing. It is a nonsensical segway into another movie and blatantly wastes its time in an uninspired zombie city building lockdown movie. Dawn of the Dead did it much better and this is just a mess. If you're still watching the movies by this point, you should know what lies ahead is so much worse. Virtua Nosedive.
