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: Dragon Ball GT
Archive Panic: Combined with the other two shows, there's 508 episodes. Each episode being about 20 minutes long, that's 170 hours of content.
Bizarro Episode: When Kaioshin drops Goku in Sugoroku Space. One minute Goku is in a fight for the Earth... And then he's playing some crazy board game.
Broken Base: The general perception of Pan by several fans. In addition to blaming her for the failure of GT, she is reviled by several fans for acting spoiled and immature, and not being as powerful as the other main characters. Yet Pan's behavior is a toned-down version of Trunks and Goten's behavior when they were children and yet neither one has faced condemnation from the fanbase because of their attitude and actions. And Word of God has stated that Pan never went Super-Saiyan because at the time he didn't know how to draw a female Super-Saiyan. Pan isn't that much different from the other characters, and yet she is reviled by the fanbase for personality traits that other characters have but they don't face the same level of derision that she does.
Ensemble Darkhorse: Sixinglong/Nuova Shenron. Fan demand even got him added to Budokai Tenkaichi 3 (his alternate outfit uses the colour scheme of his brother, Sanxinglong/Eis Shenron).
Yixinglong/Omega Shenron. Go look up silly, out-of-context GT video clips on YouTube. A good chunk of them involve Omega Shenron in some way shape or form. Not to mention his frequent inclusion in video games, even ones that otherwise exclude GT characters.
Goku and Krillin's conversation in the last episode, even more of a Heartwarming moment with the Japanese music.
Vegeta Baby making Bulma Baby his queen, in it's own creepy way...
Hilarious in Hindsight: In the episode where Earth is evacuated Goten talks with a delinquent voiced by Chris Sabat. Funimation was referencing YuYu Hakusho with both characters being voiced by YuYu Hakusho actors.
In the English dubs from Z, they made up a line in which Vegeta joked that he got stronger by doing push ups and drinking milk or juice. In the Blue Water dub of GT, Goku claims the reason for his strength is doing several push ups so now we know the difference between the two fighters.
Just Here for Godzilla: Years after the series has ended, the most iconic element of the series to really stick out for the franchise as a whole was the Super Saiyan 4 form.
Especially with all the hypothetical fan art on further evolutions based on this idea, it helps that the "Super Saiyan God" form is essentially much less impressive to look at
Memetic Badass: The fact that an elderly Krillin was able to land a hit on Goku during their friendly fight at the end of GT (Goku was obviously not fighting at full power) has prompted a meme that Old Man Krillin is the biggest Badass ever who could defeat anyone with ease.
Misblamed: Toriyama did not have much involvement with Dragon Ball GT outside of the basic designs for Goku, Trunks, Pan and various mechanical designs.
Moment Of Awesome: Goku going Golden Oozaru Super Saiyan once he finally manages to grow his tail back, and has a rematch with Baby possessed Vegeta.
The Golden Ape transformation alone totally makes up for GT's existance.
When Goku comes out of the crater holding a spirit bomb.
Moral Event Horizon: Baby attacking his own mind controlled citizens and trying to destroy the Earth simply because he knows it'd hurt Goku. And even mind-controlled they weren't willing to die for Baby's cause; they were crying and shivering with fear.
No Such Thing as Bad Publicity: In a meta-sense, it was used deliberately by FUNimation when marketing the series in North America. At first, they started their releases with the 17th episode and made their own recap of the first 16 ("A Grand Problem"), ostensibly to jump straight into the more action-oriented part of the series. The heat they took from the fanboys was intense. Once the first 16 episodes were being put out as "Lost Episodes", however, the goal they'd had all along became apparent: to generate demand for the less-appreciated earlier episodes through fan outrage. Mission accomplished.
Recycled Script: The Super 17 saga and the villains escaping from hell was literally a retake on the Dragon Ball Z movie Fusion Reborn.
The story of Zoonama, a minor villain from episodes 7 and 8, is a repeat of Oolong's origin story from the original Dragon Ball with the sole exception that, unlike Oolong, Zoonama does not become a recurring character.
The lead up to Baby was recycled almost entirely from a 1993 video game, Dragon Ball Z Gaiden: Saiyajin Zetsumetsu Keikaku, about an evil alien scientist with a vendetta against the Saiyans who created a fearsome monster to destroy the remaining Saiyans.
Scapegoat Creator: In an odd reversal, many detractors of the series point to Akira Toriyama's lack of involvement in the show's creative process. In reality, he was involved to a degree (he named the series, drew the logo, acted as a consultant for plot ideas, and designed the aged characters. So, yes, Toriyama was the one who gave Vegeta a flat-top and mustache), and going further than that, he's stated several times he's actually a big fan of the series. He even doodled a sketch of Super Saiyan 4 Goku on the side of his blurb for the GT Dragon Box. Think about that for a second: the creator of Dragon Ball drew fanart of someone else's transformation made for one of his characters.
Uub had the biggest potential out of the entire cast and he became Cannon Fodder.
You got two female Saiyans (Pan and Bra) on the show, and yet they hardly had any use in the series.
Gohan. The single most powerful character in DBZ was downgraded to the point where he had no Mystic Mode, lacked the character we had seen in Z and his full power wasn't even comparable to Goku's base form, getting Demoted to Extra and becoming a mook for Baby and lasting about 5 seconds total against Super 17 and Omega Shenron.
Goten and Trunks. Characters with remarkable potential far exceeding their fathers became nothing more than a bunch of Batteries. Eventually the trope swept away every character not named Goku.
There are lots of good ideas for epic story arcs, like the vengeance of the Tuffle race, the return of Android 17 as a villain manipulated by Dr. Gero, and fighting an evil version of Shenlong.
And not a story arc, but they spent over a year on this series and never had Pan go Super Saiyan (at least not in an unambiguous way).
So Okay, It's Average: Now that the dust has mostly settled, most fans seem to view GT as having a few very good ideas that were poorly executed and overshadowed by some of the less savory decisions and designs. It's not a bad series but certainly could've been better written.
