Spoilers----Heflin shouda punched out Sloane and then left with his wife. Agree with one review here that the ending left a sour taste. Read Vonnegut's short story "A Deer in the Works", written around the same time. The protaganist did the right thing there, but not in 'Patterns'.
Some good acting by Heflin, but Sloane's perfomance was over done. Fault that to Serling.
