The Cottage (2008)
This is a fun genre mashup in the same vein as Botched, as it starts out as a crime-gone-wrong movie. The Cottage is more up-beat than Botched, but still manages to be pretty dang gory.
The plot starts out like this: David (Andy Serkis) has recruited his brother (Reece Shearsmith of League of Gentlemen)
to help him with a kidnaping-for-ransom scheme. It doesn't seem to take long for things to go belly up and spiral completely out of control. And that's when things get exponentially worse...
Things to watch for: Andy Serkis playing an angry bad guy, fun twists all the way through, inventive gore.
