Query: Only for true horror fanatics looking for a fix.

The Ruins showed great promise when I first watched it, and it certainly did horrify and disgust me, but it failed in other ways. I didn't care a bit about any of the characters, so it didn't matter to me if they lived or died. The plot was a little flimsy (where did those particular plants come from? what made them act like that?), but they did stick to it pretty well, I think. And the effects were top-notch. But after watching it the one time, I haven't wanted to see it again, and one of the ways I know if I like a horror movie is if it leaves me wanting to watch it over to get all the nuances. This one just didn't to that. It was a one-time thing. I think more could have been done with the special effects, and the actors could have tried to build a little more rapport with each other.
