The Experiment (filmed 2005, release 2008).  4.5 forgetful horns up out of 8.   This movie came up in our list for horror on Amazon, hard to find a trailer or any info about it so we gave it a view!  The film is more of a mystery/thriller than horror,  but it’s not a bad view.   A woman gets dumped out a truck, wakes up with no memory of who she is.  She meets a man who also has no memory. They have to figure out what is up.  That’s the strength of this movie as you guess along.    VioletHör gives it 2 horns of 4.  Was going to give it 1.5, but the abrupt surprise ending bumped it up.  Kevin131 gives it 2.5 of 4.
