My favorite movie of all time is a tie between Halloween and the Thing but those are pretty much universally loved. The one movie that I've seen probably no joke about a thousand times is The Faculty. Easily my favorite of the teen horror movies of the late 90s. It's so quotable, the characters are so good, and the homages are fucking spectacular. From Dusk Til Dawn is amazing and you can tell Tarantino wrote the first half because the movie gets interesting once they get into the bar and leave the silly sociopathic shit in the first half alone.
