i thought that part was completely random and yea when sammie died it was very sad...those were vampires not zombies...it's not the traditional ones you think nor was it suppose to be

They were afraid of crosses, garlic and sunlight in the book. They technically were not vampires, they just had a photosensitive virus that auto-respired (they were afraid of garlic and crosses because they thought they were vampires). If they got shot they wouldn't die, because the virus was literally keeping them moving. They were not super strong or super smart though.

But in the film they were... what? I dunno, superhuman.

They were in fact strong, strong enough to break the class. They were vampiresque. Zombies or vampires are technically a "virus". In this case they still fed off of blood as the usual zombie vampire and had sharp teeth. They were not necessarily photosensitive, but were indeed sensitive to UV a classic vampire trait. As you can see they were still out in the day, as long as they were shadows. They were smart enough to set up the same trap that fell upon the main villain's wife/spouse/partner and they indeed did feel not like a traditional zombie. It's not like a zombie or a vampire gets shot and not die.

umm a lil to much thought was put into that i think.

did anyone see the sex scene with the girl from the video store? fucking hot! i wish it wasn't cut from the film.
