Synopsis: A scientist–whom we know is not a scientist because he’s not one-track mind crazy–comes back in time to “observe” the Enterprise crew in a crisis.
Memory Alpha Summary: Would be lower on list, but Robin Williams couldn’t play the part
Review: A rather inane episode for thirty-five minutes or so until Picard and Rasmussen have their one-on-one in the ready room when Picard begs him to let him know what the future holds. It’s a pretty awesome confrontation. Then we have the not surprising at all ‘gotcha’ ending when Rasmussen is apprehended. What bothers me is that the spacecraft from the 26th century disappears, presumably to the past, and nobody seems to care. Isn’t that a really, really bad thing that was proven by Biff Tannen with the Grace Sports Almanac?
Death By Troggles 
I’m not sure if I’m the only one that ever saw the Max Headroom pilot, but it was actually a pretty good cyberpunk story. That it morphed into the inane Cinemax interview show was bad enough, but I doubt that 10% of the viewers even knew why Max “stuttered” or how he got his name in the first place. Edison Carter was Matt Frewer’s best character, and the rest were just his smarmy self over and over again.
Count me as one of those who never saw the original Max Headroom.
I almost used the term smarmy to describe him here. It’s perfect.
typical British treatment, but not bad for its time
I wasn’t bored watching that, though I felt it was a bit…obvious at times.
