Um...there was no Night of the Living Dead II or III (the sequels were called Dawn of the Dead and Day of the Dead, so other that the "dead" part you could not tell they were sequels). I think you are confusing the movie series "Return of the Living Dead" with Night of the Living Dead. Return of the Living Dead is a pretty good comedy/horror movie series, though the third one was dead serious (and thus not that good). If you see a group of punk-rock kids getting eaten by the zombies, and the zombies are going "Brains!", then you are watching Return of the Living Dead (first one). Night of the Living Dead happens in a farmhouse for the most part; Return of the Living Dead happens between a cemetary, funeral parlor, and medical supply shop (all next door to each other). I only saw Return of the Living Dead II once, and it was mediocre. Return of the Living Dead III you can tell because a young woman is the main zombie.

Don't want to spoil too much, so I would recommend going by the video rental place and picking up Night of the Living Dead (not the version that came out in 1980, that is the god awful one; the pictures on the cover will be in black and white for the good version), Dawn of the Dead, and Return of the Living Dead (I at least, and maybe II). If you are still not "zombied out" by that point, pick up 28 Days Later. All decent zombie flicks. Oh, and another poor one to avoid is Zombie.
