Loved this Episode of Outer Limits, funny, touching Controlled Experiment
25 May 2018 | by runbamberunSee all my reviews

I was amazed to find this episode of Outer Limits, which I'd never seen before! . OL usually scares the crap out of me, and has since I first watched it as a child (older now!") So this episode was a pleasant surprise! Suspenseful to a point and too many special effects and noise but overall this one got me smiling. There is hope for change and humor. Great episode! Left me in a good mood and ready for bed. Recommended.
