Despite being on MST3K, Gemini Man has a few good things going for it. Namely, a fairly good acting talents (one has to wonder if it's the writing that's awkward or the actors, I choose the latter) and a quite original idea: invisibility for only a short time before all bets are off and SOMETHING will happen. One gets the feeling that this SOMETHING would have made an interesting cliffhanging season finale if this series had continued.
But nevertheless, the show was more a fistfight than an academic bout. Despite it's background, don't mistake the show for cerebral ground: the producers chose Ben Murphy for fighting alone. The rest of the cast, through competant, really don't stand out.
Bottom Line: Watch "Gemini Man" if you want something along the lines of "Knight Rider," but without the bad flashbacks to a certain actor's "Baywatch" career. It's just harmless fun, either if you're getting into it or just laughing and remembering "Riding With Death."
Not that bad of a series.
