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.
Better on DVD: The series pretty clearly works better as a longer narrative, considering that several episodes can easily be watched seamlessly. Has Cartoon Network realized this and capitalized on it with a DVD release? No!
Complete Monster: General Modula was originally a reasonable, heroic man, but all of the good traits Modula once had withered and died when his former best friend, the King of Galaluna, mistakenly left him for dead. Possessing now only a lust for vengeance against his former comrade, and a thirst for conquest, Modula betrayed his homeworld to the Mutradi monsters and slaughtered and enslaved its inhabitants. Fearing that only the princess of Galaluna, Illana, can restore the hopes of the planet's people and have them rally against him, Modula sends countless monsters to ravage the planet where she's hiding out. It's made clear in the show that the buildings and cities his monsters destroy are not conveniently empty, and at one point Modula goes so far as to send a living bomb capable of wiping out a planet to earth all so he can kill one girl. While seemingly stoic on the outside, in actuality Modula is utterly Ax-Crazy and is willing to kill anyone, even his own minions, at the drop of a hat. Instances of this can be seen when he smiles as he snaps the neck of a resistance fighter and when he casually vaporizes a minion who had failed him without even getting up from his chair.
A large amount of the fandom seems to be under the impression that Lance and Ilana actually ARE siblings. Nice job watching the pilot, guys.
And then there are those who blame Sym-Bionic Titan's cancellation on The Problem Solverz despite the fact that it was greenlit long before any decisions on Titan would have been made. Look at the "Help Sym-Bionic Titan Get Another Season" Facebook group and you'll see plenty of posts still blaming and blindly bashing the show.
Fan Myopia: It might be justified because of the series' short life span, but fans will make this show out to be CN's only saving grace to outside observers, disregardingtheothergoodshowsonitsline-up and promising to boycott any CN show that appears until the show gets a second season. Which will work, right? The kicker? They tend to also forget Genndy Tartakovsky left CN to work for Sony shortly after the series ended. The protest was doomed almost from the beginning.
He's Just Hiding: Many Galalunians thought this about Edward, as did Lance at first.
The Problem Solverz took over Symbionic Titan's timeslot after the latter got cancelled. Problem Solverz was a show previously rejected by Adult Swim. Now that both shows are cancelled, Adult Swim actually choose the former to air on the Toonami block.
Inferred Holocaust: Besides the huge amounts of property damage, the human casualties during the battles between the Titan and Mutraddi monsters in populated areas is downplayed, even though entire city blocks are casually wiped out every few seconds.
During the televised Titan debate in episode 3, Steel counters the commentator's saying the Titan saved them from the fire monster by pointing out that it's probably the Titan's fault the monster showed up in the first place. This is technically true, although in his case there's no way he could have known it.
During the first episode, Lance's argument for not fighting the Fire Elemental Monster makes a large amount of sense.
Barb's face is pretty creepy, and the constant smile isn't helping. Actually, any human's face, if you look too closely at it... But this is typical of Tartakovsky's art style.
Octus will occasionally do things that fall into this —little things here and there that sometimes make him seem like an old man in a teenager's body. More egregiously, the first time he showed off his Super Speed, it was to run home as Newton to save Ilana and Lance. Through a busy city, and stopping for all the crosswalk signals.
It's not a good idea to transform into a giant robot IN PUBLIC.
Even though it's a given for his General Ripper persona, General Steel's thickheadedness, lack of sense, and refusal to listen to reason leaves one to wonder as to how come he hasn't been sacked for gross incompetence.
