_**It's all about the last act**_ "Solstice" (2008) was made by the creator of "The Blair Witch Project", Daniel Myrick, and is a more conventional horror flick. Like "Blair," "Solstice" takes the subtle route with the creep factor and the typical trappings of slasher or quasi-slasher flicks; so stay away if you need serious gore, sex and nudity with your horror. The film runs 90 minutes and the first hour plays out like myriad other monster/ghost movies -- a group of youths venture to some secluded area to party and tensions increase as the creep factor increases.
