Again, off-screen rescue.
In before "Hey it's not showed on-screen or even mentioned, so it never happened."
I'm more with Solo the Wingman on this one. If they mentioned doing it, or intending to do it, I'd be fine with it. But just saying "they did it but just never mentioned it on screen" doesn't sit right with me. Part of the rules of the medium is that major events will be shown if they happen. Otherwise we would have extra States appearing from nowhere and/or characters appearing and disappearing at random. Certain things are reasonable enough that they can be presumed - I assume Shun and Miu are actually attending their university courses even though we never see them there. Other things you can't just assume they did without mentioning it. I can presume that Gentaro and Miu were secretly dating ever since prom and just not mentioning it to save Shun's feelings and stop Gentaro loosing the power of Cosmic. But nothing in the narrative suggests that, so I can't just take it as given that a major event like that could happen and just not get mentioned (sorry Gen/Miu shippers). My feeling is that rescuing fairly important secondary villains is big enough that it would warrant at least a mention if it happened off-screen. They only had to mention it in a single passing line and I'd accept it happening even if they didn't show it. As things stand, it's as valid to say that Virgo only teleported Tomoko and Ryusei to M-Bus and actually was throwing the others into the dark nebula to certain doom.
Gobusters hasn't ended. And how can you honestly think it is better than Fourze? I mean, while I will always take Sentai over Rider, Gobusters has had little to no plot as opposed to Fourze which was always advancing the plot. And really, OOO before W?
Actually, forget that, how can you like Decade better than Fourze when Decade did not even get an actual ending?
I'd consider myself to be a Rider fan before a Sentai fan. Of the first dozen toku series I watched, eleven of them were Rider shows (Kuuga through Double) and only one was a Sentai (Shinkenger). But I'd take Go-Busters over Fourze. There are things I've enjoyed about both shows, but Fourze has at times managed to piss me off in a way that Go-Busters has yet to do. Go-Busters is the one I most looked forward to each week, often watching it as soon as possible, while leaving Fourze to whenever I had some spare time later in the week. Similarly, Decade was the first Kamen Rider series I ever saw, and it managed to ignite a love for the franchise that has made me track down and watch almost every episode, film, and special in the franchise made since 1990, and as such it has something of a special status that gives it a free pass as far as I'm concerned. I can see all the flaws it has, but there were good things about it too. I know there's another thread at the moment for listing your favourite rider series in order of preference, and while I don't know where Fourze would go in it yet (I like to give a show some time before I give a final verdict on it) I'm sure Decade would be in the top half of my list.
I know they graduated. But 18 is an age to get married? If it was as a normal present to try to rekindle their relationship, then fine. But I just find it hard to buy that he wanted to get married that young, especially in modern Japan.
Shun's only personality trait is his unrequited love for Miu, who true to type, blew him off (though he never actually asks her, it's just her reaction that suggests it). I know people who've got engaged at 18. It's rarer in modern first-world countries, but not unheard of. Tbh I just took it as one last gag at butt-monkey Shun's expense.
