When it comes to the movie that put Romero on the map I'm divided between the black and white 1968 original and Tom Savini's 1990 remake. Most people would agree remakes of movies aren't as good as the originals. I can think of a few that buck the trend and the 1990 remake of Night of the Living Dead is one of those for me. Having seen both versions multiple times I just seem to gravitate to the 90's version for several reasons.
1) Color. It makes a difference. Alfred Hitchcock may have made some great black & white movies in his time, but seeing everything happen in vivid colors makes a lot of difference in my book.
2) The actors and actresses. I love Tony Todd and his character of Ben in the 90's version is better. Same goes for Patricia Tallman as Barbara. The original actress that portrayed Barbara was so freakin' annoying in the 1968 movie. At least we see this new version of Barbara get over her fear and fight back.
3) Tom Savini! I love gore in my horror movies and Tom did a great job with the updated special effects in the 1990 version.
4) The ending. If you haven't seen either version (what have you been doing? Seriously!) then I don't want to spoil it for you. I just find the end of the 1990 remake that much better and satisfying.
While I love all of (Romero's) sequels that spawned from this movie there is just something so special about the original - whether you prefer 1968 or 1990 - both are classic movies that deserved to be watched each October.
