Shaun of the Dead is a good comedy twist to the movie Dawn of the Dead. Loved the part when they where killing the Bartender zombie to the beat to Don't stop me now.
The Day the Earth Stood Still is good for people who have never seen the original or read the book.
War of the Worlds was a decent take of the book from another's perspective.
Alien series.
Do it. Now! Also watch the Predator series.
Twilight
Nuff said.
Night of the Living Dead good for a late night watch if you like older movies.
I am Legend has only two things wrong with it.
SPOILERThey did not go into detail on what created the zombies or why. THey just mention it was due to some cure for a disease.
Dawn of the Dead is a more modern "yet another typical zombie movie". Now with more "dogs can live".
Also a note to the title, It could fit better if it was titled "Any good creature movies?"
