Ya missed one of my favorites, "Vrilliance".
Weird. I'm not even getting it on Google either.
In any case, easily my favorites.
Along the same lines, except here on Earth - and while it was a bit more out of control and hopeless for the explorers - I enjoyed the heck out of Slider's as well, Although I am convinced Quinn Mallory was actually initially lured into the device by his evil twin brother who assumed his life.
And again similar, with the exception of how mean it seemed to be placing the lead character - against his will - into unpredictable female and male forms involuntarily - was Quantum leap with Scott Bakula,
I mean. like the show Vrilliance, it wouldn't suck to 'play the part' of a female just to 'feel what it felt like' - but to be slipping and sliding willy nilly to these other forms and places like in these shows would drive me absolutely insane!
