History YMMV / LostInSpace

* {{Narm}}: Hoo boy. Probably most notable is the episode "The Great Vegetable Rebellion," where Mark Goddard has noted that during several shots you can see him deliberately not looking at the [[PlantPerson vegetable people]] so he wouldn't laugh. Peter Packer (the episode's writer) openly admitted he was completely out of ideas after three years (he wrote 24 episodes, which is still quite a run).

* SpiritualSuccessor: With its family in a scifi environment, cloaked MadScientist villain, a plot centered around a doomed space mission, along with a lot of similarities in the characters' personalities and appearances, on top of encounters with weird aliens, parallel timelines, BadFutures, Lost in Space could be closest thing spiritually to a live-action ComicBook/FantasticFour movie, albeit with one where they didn't get powers, and there were some composite and de-composite characters. Will Robinson and Penny even look like Franklin Richards and Valeria!

* WTHCastingAgency:
** Creator/MattLeBlanc as Major West. Although the film's bad enough, [[TookTheBadFilmSeriously and he plays every one-liner so straight,]] that imagining it as something [[Series/{{Friends}} Joey's]] been cast in [[SoBadItsGood actually improves it quite a lot.]]
** A lot of criticism was sent Creator/WilliamHurt's way, who was anchoring a summer effects-laden sci-fi popcorn film and his approach was virtually the same as his very dramatic roles, which didn't help when he needed to deliver wooden dialogue such as "I love you, wife".
** Creator/HeatherGraham as Judy was very blatantly a case of someone being cast to act as MsFanservice rather than because she was suited to the role. It says something that, even with all the criticisms thrown at Hurt and [=LeBlanc=], Graham's performance is widely considered to be hands-down the worst in the film.

* EnsembleDarkhorse: Dr. Smith and the Robot were by far the most popular characters, with Creator/JonathanHarris himself calling them the whole reason anyone watched the show. Funnily enough, neither was in the original pilot and we have an extensive {{Retool}} before the main production to thank for their existence.

* VillainDecay: Doctor Smith went from a fiend planning to [[KillEmAll kill everyone on the ship]] for some vague reason to a [[JerkWithAHeartOfGold prissy jerk who actually saved the crew sometimes]]. Unusually, this was actually at the request of Creator/JonathanHarris, who feared that Smith would soon be killed off if he continued being a threatening villain.

* HamAndCheese: Creator/GaryOldman as Dr. Smith. And he seems to get increasingly hammy over the course of the film. Initially, he starts out somewhat restrained, but once he's trapped in space with the Robinsons it's like he's given up all attempts to be subtle. He openly admits to being a monster and evil at every given opportunity with what could only be described as sheer glee. His antics on the Proteus in particular are on par with a Saturday morning cartoon villain. [[UpToEleven Then there's Spider-Smith...]]

* FandomRivalry: Some ''Franchise/StarTrek'' fans are rather cold with ''Lost in Space'' due to its hand in getting ''[[Series/StarTrekTheOriginalSeries The Original Series]]'' ScrewedByTheNetwork as well as in perpetuating the notion, popular among American television execs at the time and which ''Star Trek'' helped dispel alongside ''Series/{{The Twilight Zone|1959}}'' and ''Series/{{The Outer Limits|1963}}'', that [[SciFiGhetto sci-fi could never be considered "true art"]] and therefore [[LowestCommonDenominator should not aspire to be]].

* EnsembleDarkHorse: In a film filled characters who stand out as being forgettable at best and annoying at worst, Dr. Smith and Penny Robinson are the only ones who bring any life to the proceedings, with Smith being an entertainingly over-the-top LargeHam of a villain, and Penny's DeadpanSnarker moments giving her most of the genuinely funny moments.

%%* {{Narm}}: "I love you, wife." NarmCharm depending on your mood.

* NeverLiveItDown: As noted, "The Great Vegetable Rebellion". Even the show's staunchest defenders won't stand up for this one, including the cast and crew (Bill Mumy admitted in an interview for the Archive of American Television that he was embarrassed by it even at the time), and it made it to ''Literature/WhatWereTheyThinkingThe100DumbestEventsInTelevisionHistory'' at #24.

* WhatAnIdiot: In the movie, [[spoiler: John discovered Future-Will had built a working time machine with enough power for a single one-way trip. When he sees his ship along with his family perish in a meteor shower in the atmosphere of the planet, he decides to use the time machine to travel back a few minutes and prevent their deaths. Sounds all well and good, if you don't take into consideration he could've just gone back to the day of the shuttle launch that sent him and his family spiralling through time and space to unknown reaches of the galaxy and prevent the entire plot of the movie. The movie attempts to justify this by having John worry that Will's time machine might destroy Earth, as it was destroying the planet it was built on, but that conclusion was a guess at best, and as a matter of fact Will had already connected to Earth before changing the coordinates.]]

* RetroactiveRecognition: The future Will Robinson they encounter is Creator/JaredHarris, a decade before ''Series/{{Fringe}}'' and ''Series/MadMen''.

* CompleteMonster: [[MorallyAmbiguousDoctorate Dr. Zachary Smith]] was already a self-serving sociopath who tried to murder the entire Robinson family [[{{Greed}} just to make a quick buck]]. However, it isn't until later, through the means of time travel, that we see how truly monstrous he can become. When the botched assassination ended with him stranded on an alien planet with the family, Smith mutated into a monstrous spider-like creature who murdered and possibly ate the defenseless Maureen, Judy, and Penny Robinson, then manipulated young Will into building a time machine in order to save his family from death, all the while making Will see him as a father figure. When Smith meets his past self, he mocks him for lacking "true ambition" before attempting to murder him. After Will completes the time machine nearly two decades later, Smith tries to kill him while revealing his master plan to use the machine to travel to Earth, then unleash a horde of spider monsters to ravage the planet and [[AGodAmI rule over them as a god]]. [[AdaptationalVillainy In a sharp contrast]] from his [[Series/LostInSpace original humorous and clumsy incarnation]], Dr. Smith is a truly wicked individual who [[ItsAllAboutMe cares for nothing but himself]].

* CompleteMonster: [[MorallyAmbiguousDoctorate Dr. Zachary Smith]] was already a self-serving sociopath throughout this film, however it isn't until later, through the means of time travel, that we see his truly monstrous future self.

However, when the botched assassination ended with him stranded on an alien planet with the family, Smith showed himself to be an absolutely depraved monster.

** Blarp the CGI spider monkey. Looks less convincing than an equally cheap-looking puppet, and assuredly was more expensive.
** Dr. Smith's alien-spider form is a treasure trove of badness. It's badly composited into the practical-effects cloak he starts with--his head rapidly wobbles in his hood. The actual design is almost impressive, except for the hugely long neck that makes no sense given he was mutated by {{Cephalothorax}} space spiders. In action, it lacks weight and doesn't quite line up with the set or actors.
