Not bad, but average for a Twilight Zone episode. Written by Rod Serling and He's Alive has a few good plot twists and a surprised dark figure. The social message become old with the redundant lurking evil story line we see through out the T V series. But W W 2 was fresh in society's mind back in the early 60's which must had an influence with Serling. I believe evil will be the same but transform into a different unpredictable spin, which I think could have helped with the script. What shines and save He's Alive is Dennis Hopper character shines as Peter Vollmer a Nazi wannabe. One feels and experiences the Vollmer character. Adolf Hitler/mystery character was very accurate an chilling. Stuart Rosenberg directed He's Alive with the proper ebbs and flows, with highs and lows, which mixes characters with each act. 6 out of 10 stars.
