Placeholder I'll update later:
Tales from the Hood - This one is a classic IMO. Not the greatest horror movie ever made but it's certainly different enough that I remembered the scenes after not seeing it for nearly 20 years.
This Is The End - I thought it was great until roughly the last 30 until it started to drag a little.
Blackfish - I'm not a big fan of animals in captivity as it is but this certainly convinced me not to go to SeaWorld.
Europa Report - I highly recommend this sci-fi film. Not much of a plot (follows the journey of a crew to Jupiter's moon, Europa) but was still interesting to watch. The editing was poorly done IMO and it's confusing in the beginning what is actually going on.
Singapore Sling - W. T. F.? Obviously I was expecting a weird movie but the IMDB doesn't do it credit with how strange and disturbing this was. What really separates this from the usual shock for shock's value is that it's an extremely well made movie.
