Tokusatsu has always been a cash train, ever since Kamen Rider and Super Sentai was a thing. Recently, they’ve been doing “collectable gimmicks” for their series to sell even more toys.
Whether this is a good or bad thing depends on if the show itself is still good.
It also depends if the gimmicks are actually an original idea and arent just cheap things like cards with the characters printed on them. Luckily most of them are just fine, and I still end up trying to buy some of these strange new toys. But, this is of course all up to you.
