Did You Know?


The premise of this show, which was that the title character's genetic quirk made him a criminal, has now been disproved; in fact the show would've been vastly more interesting had he been an XX chromosome man (that is, an estrogen resistant female) because then his infertility would've given him more reason to turn criminal.

Dated, worthless television rubbish.

I can't believe I actually bought this old tosh on DVD. What was I thinking?? This series only lasted 13 episodes (mercifully) and I struggled with the first 4 episodes. After that, I stopped watching and I sold the DVD set. The plots are so absurd, they defy description. The leading man is OK but not outstanding - he quickly faded into obscurity. The look of the series is so dated, it began to age even before transmission came to an end!! The only reason to glance at "The XYY Man," is Don Henderson as the Detective Sergeant Bulman. The series that followed which made his character the lead, "Strangers," is a much better made programme in all respects. Avoid "The XYY Man" series at all costs!
