I have a feeling I'll be flamed for this but...
ToQger is my favourite Sentai series. The last couple episodes have been pretty boring, but I've been having a lot of fun watching it overall.
Another unpopular opinion but...I think people severely overrate the significance of writing in Sentai. There's limits to what writers can do based on the toys they are given to play with,
literally and figuratively. I really don't understand why writing is so scrutinized in Sentai compared to Rider (in general), there's a lot more flexibility in Rider (adult characters, arc structure, more out-of-suit/non voice exclusive actors to work with). I think Kobayashi has done an admirable job with ToQger. Every character has entertaining arcs that pays off slowly throughout the series. Whilst maintaining an interesting overarching plot that actually progresses! The majority of it is very well and carefully crafted, with a few hiccups along the way.
Correct me if I'm wrong, "writing" in Sentai and Rider is meant to provide a path and a direction for a story. The main draw for these shows are the suits, the action. Otherwise there are plenty of dramas and television shows that explore themes much more in-depth. Therefore, writing should enhance and complement this idea that it's about "SENTAI!" and "RIDERS!" or superheroes! Or at the very least meld and complement each other (Shinken, W) I know that's a contentious point, and it is in no way absolute, nor have I conveyed that argument well. HOWEVER it needs to be kept in mind as I express my own opinion on ToQger. And in that sense ToQger has done a fantastic job, its a lot of fun!
That and many other shows are pretty much determined by the character setting and the toy line. If Tokacchi's a dork he's going to stay a dork, or else he's someone he's not. Honestly the biggest payoff every year for me in Sentai, is seeing them go from crappy actors to serviceable ones. It makes such a huge difference in their characters (Alata from Goseiger ep 1 to the finale). It depends so much on things outside of the writer's control. In regards to toy line we remember the minor hiccup with Baron getting Lemon Energy, it wasn't very clear in the context of the show how that's possible. But Baron needed an upgrade, so...tada! (They should have just spread out Jimber upgrades to everyone, easy to make)
Honestly, I feel OP's complaint can be applied to any Sentai series. That's really not what I'm looking for from Sentai.
The cast of ToQger are a bunch of morons. And that's exactly why I like them, it conveys the spirit of Sentai, they're not "adults". They're a group of innocent "kids" that received these superpowers and are trying to make a difference in people's lives whilst saving their hometown. That's why it feels like they're your buddies and they're the good guys, defenders of justice!
That's not to say it's not "dark" the collateral building damage and "deaths" in most Sentai puts something as "dark" as Gaim to shame. The tone doesen't necessarily determine whether it's a serious show or not. This modern day obsession in media for stuff that "appears" to be dark at face value is getting really old, it's also pretty lazy. The themes they expressed early on with the villains were
dark as hell. The stuff they do to drive people to despair ranges from as innocent as toothaches to kidnapping children, or forcing people to duel each other. There's already been a bunch of episodes with "if you don't do X by a certain time, you're alllllll going to die". The politics of the villains has also been wonderful to watch. Mamoru Miyano as Baron Nero has been great, and Zett oh my god Zett is my favourite Sentai villain. What a badass.
With a concept like trains, there is no cultural or historical treasure trove of drama you can delve in to like Samurai, Ninja's or sentient Car animals
. Train otaku aside lol. Early on, the idea of transferring, passes and colour changes was fresh and new. It helps to offset some of the staleness that comes when you run out of power ups in the show.
My biggest issue with ToQger is that the toy line really slowed down in the second half. The Hyper powerup is a really boring and safe choice. There's no reason for it to be user exclusive besides "Oh Shinkenger had it, Kobayashi's the writer, makes sense" but it actually made sense in Shinkenger thematically. For this it just feels like a present/reward for whoever has a character episode that week. Good job! you get to take the shiny golden train for a spin! Or at the very least put more work into it than just a plastic golden chest piece.
Mecha! clusterfuck. In the span of about 10 episodes we've seen a bunch of collective mecha upgrades. It's gotten bigger and bigger and bigger, to the points where it's like oh cmon now. Again, I don't know whether it's tradition or not (Kobayashi did Shinkenger, therefore 6 member team!), but a 7th ranger or something similar would have been a decent alternative to rushing out mecha. It fits as well, the idea of the 7 colours of the Rainbow Line. Holding out for Zett to be a Purple ToQger
.
I often feel I have such polarizing opinions to the Sentai fan community on writing and evaluating the "light hearted fun Sentai". So maybe it's just me. I mean, to everyone's horror. Goseiger IS my second favourite Sentai series...(gasp).
