DETENTION - A favorite of mine. So wacky, quick, and smart.
MINE GAMES - This was a fun watch. I popped it on thinking it was going to be a yawner, but ended up riveted by the 30 minute mark.
LAST SHIFT - Another fun sleeper hit. twisted and highly entertaining.
PLUS ONE - Another one I thought I'd sleepwalk through tat turned out to be highly engaging!
Time Crimes -
I really dug TIME CRIMES. It had that WTF?! quality I love with a complex little story that had me super happy by the end of it. The time loops and story twists are super entertaining and very interesting. I can't really explain the story without giving it away. Suffice it to say that there's a mystery that the rather plain Héctor stumbles into is something he just might have to kill for.
Time Lapse -
IMDB describes it well:
Three friends discover a mysterious machine that takes pictures 24hrs into the future and conspire to use it for personal gain, until disturbing and dangerous images begin to develop.
This one starts out slow, but it really starts to build to a fantastic climax. It has a downward spiral that works like watching a train wreck in slow motion. It's fantastic to watch the horrors of the ending unfold. hhehehe
