while the twilight zone be a wonderful show and it be also very uneven with some great episode and some lousy one and many in between . don not believe the die hard fan there be some stinker and this be definitely one of them . in a plot that be obviously mean to be an attack on fidel castro and a near lookalike ( peter falk in lot of makeup and a beard ) obtain a magic mirror that allow him to realize who all his enemy be so he can liquidate them . while i do believe that castro be a thug and dictator ( and ten of thousand of refugee and political prisoner will attest to this ) and it amaze how this sort of preachy episode actually make audience laugh at the american effort to marginalize the creep and actually make castro seem okay . think about it serling and company want to hurt castro but instead only seem to be obvious and preachy and silly in the process . it indeed bad almost laughably bad when see today .
