- Alternative Character Interpretation:
- Doyle caused the great chipmunk fire of 1979. Bud and Doyle were revealing their darkest secrets to each other in the Bio-dome's desert thinking that they're about to die, which Doyle backed off at the last second telling the truth about the chipmunk story. Also, considering how much of a idiot Doyle appears to be, would it really be that difficult to believe that he may have somehow lit a chipmunk on fire? Doyle not being able to hold in his laughter when Mr. Leaky brings up the fire again later on could be taken as a moment where Doyle finds it unbelievable that he got away with starting a fire that became a legend.
- What were Petra and Mimi going for when they decided to "thank" Bud and Doyle for fixing the Bio-dome? Was it just going to be a one time make-out session? Or were they aiming to start something more?
- Anvilicious: The film isn't exactly subtle with its environmental message.
- Awesome Music: Dude. Everyone likes "The Safety Dance" (and "World Destruction", too). Its inclusion in this movie is one of the few good things about the movie.
- The song "5 Needs" that plays during Tenacious D cameo in the film, which eventually got a limited release 18 years after the movie came out.
- Designated Hero: We're meant to see Bud and Doyle as the good guys, even though they spend the movie beating the shit out of themselves, acting ridiculously obnoxious and practically destroying the dome, and the majority of the stuff the scientists put all that hard work into developing. Plus their unprovoked groping/attempted rape of the female scientists in their sleep.
- Ensemble Dark Horse: Faulkner is the only likable character in the movie and he has a few awesome moments as well. The only laugh that could possibly be had in the movie comes from him.
- Fridge Logic: The two slackers had only been in the dome a few minutes. It wouldn't have damaged any year long scientific studies to boot them out and reset a few minutes.
- Idiot Plot:
- The entire film is built on this trope. Kick the morons out of the titular Bio-dome as soon as they break in, and the movie's over in 15 minutes. Leaving them in would cause more damage to the experiment than restarting the clock a few minutes later. They still aren't kicked out when even the scientists can't bear them any more!
- There's a key in part of the dome's cover that opens it up. Why would you leave a key that opens what's supposed to be a self-contained ecology in its lock? Oh, right — because they need to get Bud and Doyle outside for the plot.
- All police efforts to break into the biodome focus on destroying the incredibly strong (and undoubtedly expensive) steel time-locked door. Apparently failing to notice the entire structure is made of either glass or some type of plastic.
- How about the whole idea of locking people in someplace with absolutely no way out in the first place? Let's say Romulus or Petra takes a nasty fall and break their back. Are they just supposed to spend months in there paralyzed with no specialized medical care? Even the experiment the movie's biodome was loosely based on, Biosphere 2 in Arizona, let an injured member leave.
- Moral Event Horizon:
- Bud and Doyle cross it with their Attempted Rape of two female scientists.
- Because of the extreme degrees of annoyance that Bud and Doyle had demonstrated up to that point one can still find some sympathy for Faulkner when he abandons Bud and Doyle in the desert part of the dome to die, but when he decides to blow the dome sky-high with everybody inside, that's the moment he completely loses it.
- Nightmare Fuel: Shore's laugh after winning the "for fun" RockPaperScissors match.
- One-Scene Wonder: Tenacious D playing at an environmentalist party.
- Padding: A lot of time is spent on Bud and Doyle just messing around and having fun throughout the interior of the bio-dome. 5 to 10 minutes of this stuff could easily be shaved off from the film without missing a beat.
- Rooting for the Empire: Faulkner. In spades. His only crime seems to be being a Jerkass towards the two doofuses — but even that is perfectly explainable. Would anyone else act differently?
- They Wasted a Perfectly Good Plot: The idea of a group of people surviving inside the bio-dome, completely sealed off from the public could've easily made for an interesting premise, written seriously or for comedy. Word of God states that this was the original intent before Executive Meddling kicked in.
- Took the Bad Film Seriously: William Atherton, the one who plays Faulkner, is probably the one person that actually tried to put in a passable performance amongst the main cast.
- Unintentionally Sympathetic: You actually feel sorry for Faulkner and see why he went Ax-Crazy when you think about how much obnoxious assholes Bud and Doyle were.
- Unintentionally Unsympathetic: Bud and Doyle are practically made of this, being disrespectful towards their girlfriends, causing irreparable damage to a serious, potentially life-changing scientific study and generally acting as nothing more than irresponsible Jerkasses throughout the entire movie's length. Even by Unsympathetic Comedy Protagonist standards, they're impossible to like, let alone tolerate.
- Values Dissonance: The moment where Bud and Doyle sneak into the beds of two of the female scientists while they are sleeping and then proceeding to feel them both up before they are promptly kicked out. Even if they weren't already dating prior to their misadventures in the dome, they are both guilty of sexual assault. The fact that it is Played for Laughs does not help its case in the slightest.
YMMV / Bio-Dome
