Plot hole: Anubis Warriors can only be killed by being beheaded. But during the final battle, you see several are killed by simply being stabbed.
Plot hole: The spinosaurus manages to smash through a metal reinforced wall designed to stop dinosaurs getting past it without too much effort, yet it can't get through a wooden gate secured by some metal bars. It makes no sense.
Plot hole: When the Grundel explodes near the end, Rowan looks out the window to see Uber Jason floating towards the rescue shuttle, only to be grabbed by Brodski who happens to fly sideways at a high rate of speed. Now provided it's feasible that Uber Jason can survive an immense explosion, how Brodski not only survived the explosion but managed to wind up away from the spaceship and far enough off to the right so as to catch Jason in mid-space is beyond me.

Plot hole: When the survivors first make an attempt to break out towards the station they kill numerous assailants at close quarters and yet only one of them (Uno) is infected. There must be dozens of the parasites floating around, enough to infect them all.
Plot hole: Why can't people see the zombies until they are two feet away? Even in the daylight!!
Plot hole: Why did the killer cut off the hot water? Did he think that Dorothy would come down and turn it back on herself with all those staff members in the house?
Plot hole: When Grace Stewart sends Ann out of the music room for "lying," the hall is visible as she opens the door - with lots of light from windows bursting in. I know it turns out not to matter, but the child would have screamed.
Plot hole: Fuller is supposed to be heading to Denver, but after picking up Venna in Boulder he inexplicably stays on even after telling Lewis just before this that he was not going to be going home with them.
Plot hole: Early in the film, we learn that the former prostitute Annie Crook is married to and has an infant daughter (Alice) with Prince Edward Albert Victor. Secretly outraged, Queen Victoria dispatches various high-ranking operatives to eliminate this potential royal scandal. To that end, Prince Edward Albert Victor is secreted away, and his wife Annie Crook is kidnapped and barbarically lobotomized. We then learn that he baby, Alice (who was fortunately in the care of two other prostitutes at the time of the kidnapping), was sent to live with the parents of Annie Crook, no doubt saving the baby's life. That is the last time we hear of baby Alice until near the end of the film, where we are puzzled to learn that Alice was not sent to live with her grandparents at all, as stated earlier. Rather, the prostitute Mary Kelly took baby Alice away from an orphanage to raise as her own. No explanation is offered for this discrepancy.
Suggested correction: The Spinosaurus used its full body force to smash the fence. The gate, being a smaller target, was too small for the Spinosaurus to use its full body force.
