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.
Dude, Not Funny!: Not everyone agrees that Mio slapping Tokatti at the end of #4 is funny, given that the context in question is a case of Unprovoked Pervert Payback. It doesn't help that Wagon was teasing them, making Mio think that Tokatti did something to her. Neither does the rest of the group laughing at the scene and showing No Sympathy towards Tokatti.
Les Yay: Mio and Kagura are particularly close, even for a team as tightly-knit as the ToQGers. In any given group shot there's a good chance the two of them are side-by-side, especially in one shot where they're sharing the same seat in ToQ-Oh's cockpit (which has seats for all the ToQgers). They're actually holding hands in Station 21. Becomes more obvious since they did first in their childhood.
Most Annoying Sound/Most Wonderful Sound: The equipment speaks in a manner meant to sound like a train conductor, i.e. in a cheery monotone laden with excessive politeness and constantly repeating itself. It's also almost constantly talking during battle scenes, having easily three or four times the amount of dialogue per action as any other Sentai team's equipment. The result is that very few people are neutral on the subject of the To Q Changer's voice, though which one they consider it to be varies wildly from person to person.
Ever since Akira joined the team, the repetition has been shortened, especially during team henshins
Unfortunate Character Design: When the ToQ-Oh toy came out, people realized that they could unfold the Red Ressha and give the robot a long red cylinder extending from its crotch. Just people being people and perverting anything they get their hands on into something dirty, right? Well, no. The function shows up in-show◊ in #3, where the ToQgers use it to, er, thrust Red Ressha out of the trap they're in.
