Well considering I love both Go-Busters and ToQger and plenty of people liked Kyoryuger a lot, I'm going to go out on a limb and say that the "mediocre Sentai curse" doesn't exist in terms of overall quality outside of your personal preferences.

If you mean "is Zyuohger going to break the downward spiral Super Sentai has in terms of ratings", I'm pretty confidently going to say no even though we're only three episodes in. That isn't a reflection on the show itself, but more that I genuinely don't see Sentai breaking away from that trend any time soon.

The question is how good are the toy sales going to be, and its far too early to tell right now.
