Although not creepy or dark but indeed sci-fi, I did enjoy this episode thanks to a good pace and a great story.
We find Russ Rosenthal feeling a little off so he decides to pay a visit to his own childhood home. When he unearths an old toy soldier from the backyard he is transported back to the 50's where he meets his own younger-self. In the end we discover that the reason for all his anger was not other people but actually himself.
Well told and great ending where we are shown that other parallel universe exist and many other realities are existing at the same time as ours.
