These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Good Luck Charlie
Acceptable Targets: Nerds. Even when one becomes a minor character, his nerdiness is often poked fun at.
Not to mention Bridgit's Snub for Favorite TV Actress. While it is highly unlikely she would have beat Selena, who has the backing of the Beliebers, or Nick actresses Victoria Justice and Miranda Cosgrove, she was given the worst possible awards promo. For those who didn't see it or forgot it, they showed a scene with Alex and Mason for Selena, a scene with Carly and the smart British dude in "iQ" for Miranda, and Tori and Beck for Victoria's. What did Bridgit get? A shot from "Termite Queen" with her dad while she is on stage dressed as a Termite shooting hundreds of eggs from her rear end. Ouch. As if a scene with her and Spencer was hard to find.
And while Charlie might have a few more funny moments than Teddy, and Bridgit didn't stand a realistic chance of winning, one could argue that she was screwed by a network she doesn't even work for, how rare.
In the episode "Can You Keep a Secret?," Bob tells Gabe that in the state of Colorado they don't give money for aluminum cans. All recycling programs across all states give cash payments for aluminum cans as this is the main incentive device for recycling (and the price of aluminum is actually rising).
In "Gabe's 12 1/2 Birthday", the Duncans/Wentzes are snowed in due to a freak blizzard in what's implied to be late May (and explicitly stated to be sometime during that month). The latest snowfall recorded in the Denver area in recent history was approximately around May 15, and the heaviest snowfall record in recent history in the Denver area in May completely evaporated without a trace by late afternoon. Colorado does have a reputation of being a snowy state, but come on.
As pointed out in Headscratchers, the central problem between Amy and Bob in "Snow Show" wouldn't be an issue in Colorado, which is a common law state.
Establishing shots of the high school showing it so close to the mountains (or rather, foothills) plus the geographic implications of it being "South High" imply the series actually takes place in Littleton instead of Denver, though it's still "close enough" to call it Denver.
There was also one episode where Gabe tried to sneak into a PG-13 film even though he was 11. There are no age restrictions for a PG-13 movie, only R and NC-17 movies.
Skyler as well. Jo is very popular too.note And now they have their own shows: How To Rock (formerly) and Dog With A Blog, respectively
Family-Unfriendly Aesop: When Teddy was dating the Po-Ki-Oh player, the intended Aesop was "don't change yourself for your boyfriend," but the viewer can see it as "Don't date nerds because they have strange hobbies".
Also, in the episode where Teddy gets back together with Spencer, the only lesson that this troper could glean from that was "if a guy cheats on you, lies to you about it, and basically shows no regard for you whatsoever in doing that, it's still okay to get back together with him as long as he's hot." However, Spencer did feel guilty about it, and he nobly considered quitting his job, so that Teddy wouldn't have to feel uncomfortable so it could be taken the lesson is "If a persons truely sorry, its okay to give them another chance". To be fair though, their actors started dating in real life shortly before their characters got back together.
Possibly in "Up A Tree." The Duncan family couldn't get sleep because Mrs. Dabney got an obnoxious dog that was barking all night keeping them up. Bob agrees that if she brings the dog in at night, he'll cut down a branch causing her problems. Teddy is against it because if the branch goes so does her old tree house they don't use anymore. In the end the entire family takes her side. What's the lesson here? "Remnants of your childhood are more important than getting sleep (which you need to live) even if you don't need them anymore."
And then it turns the dog didn't belong to her, that it was someone else's dog she was taking care of and she was messing with them the whole time, which makes this entire episode pointless.
The Scrappy: Amy. Her selfish, egotistical, and just plain crazy behavior comes off as annoying and jerkish than funny. Her crowning moments of scrappiness include replacing all the members of the family except Charlie for a talent show (which was something she technically didn't apologize for), hijacking Teddie's interview for Yale for her TV show (thankfully, Teddy got in anyway), and leaving Victor trapped in a hole just so that she could do a news story on it. Additionally, she has a complete inability to get rid of her negative traits, despite every character seeing her as a nutty attention whore. Also, she manipulates her husband and kids and is teaching Charlie to do the same.
Shipper on Deck: Ivy tends to act like this towards Teddy and the Love Interest of the Episode.
Teddy and Amy tend to be this towards Gabe and his love interests.
Special Effects Failure: Actually an example of leaving special effects in when they're not called for. At the end of The Movie, we see Charlie through the perspective of Teddy's camera - but the washed-out "hand-held cam" effect is still present even after Teddy folds the hand-held cam away.
Too Dumb to Live: The kid's grandmother (mother's side). Basically, her entire approach to kids is the one she used when she was a mother, thinking it works on them all... and don't get us started on how she blames Bob for what trouble Charlie gets into, despite seeing her do so.
Toy Ship: There's a surprising amount of tension between Gabe and Jo, who are both 10.
Charlie gets a crush on a boy her age in "Snow Show."
Uncanny Valley: The talking Charlie in the "Gurgle Chat" video is pretty creepy.
The end credits gag in "Guys and Dolls" intentionally invokes the Uncanny Valley with a "life-size Teddy doll."
Sadly Truth in Television depending on the company. Huge companies get under fire for even implying anything gay is happening; a much smaller one like the one Teddy worked for would likely fire her to appease angry parents.
Unintentionally Unsympathetic: It's extremely hard to root for Amy, considering her selfish behavior and the fact that she causes most of her conflicts in the first place (witness "Amy Needs A Shower" - "It's nobody's fault," she says twice towards the end. No, Amy, it's your fault).
Not to mention that she causes the entire B-plot problem in Special Delivery, as she forgets to arrange Charlie's birthday despite her doing nothing but eating that whole time. This could be forgiven, as she was still in her pregnancy period.
The Woobie: Alice Wartheimer. Poor girl has asthma, is teased at school, has no friends, and was regularly yelled at by her boss for no apparent reason. When she tells Teddy that she was the only person who went to her Arbor Day party, you can't help but feel sorry for her. And then there's her last name...
Bob rarely gets any respect from anyone and his wife steps all over him.
