The Enterprise sets out to help the colonized planet Penthara IV, where an asteroid impacts with an apocalyptic effect, first scorching then lasting clouding comparable to nuclear winter. En route to it, an unknown vessel appears after a temporal distortion and beams aboard history professor Berlingoff Rasmussen from Earth three centuries later (the 26th), who is obsessed by Picard, who expects the whole crew to be questioned, despite the possibilities of fraud or altering reality. Once at Penthara IV, Geordi on the planet and Data aboard devise a method to create a greenhouse-effect, at the risk of making it far worse, so Picard wrestles with using Rasmussen's hindsight, but his own history proves significantly problematic.

A Sillier, Filler Episode That Stays With You
17 September 2020 | by frankeleeSee all my reviews

Max Headroom comes aboard the Enterprise as a time traveler from 200-300 years in the future to watch as they attempt to save a colony world from destruction. Matt Frewer chews the scenery around the Enterprise, not as a mustache twirling villain, but as an unbelievably annoying cad. Without spoiling anything, you know something's got to be wrong with this guy within seconds. That unsubtle approach makes this episode clearly marked out as a light-hearted one, even though a planet faces total destruction, you're not supposed to take things too seriously here.

Still it's an episode I remember watching the first time, way back when it aired on an actual broadcast, likely thanks to Frewer's ridiculous professor and the somewhat interesting twist at the end.
