ToQger doesn't get complains about red being over sold. It just gets disliked for being too childish (Yes, I know that they actually are children, not the point). Everyone has a level of silliness and goofiness they can take, especially for a series like Super Sentai. Even though the franchise is inherently silly, there's just a threshold that can be crossed, and some people felt ToQ crossed that particular line (Or track).

Ninnin people dislike for being too red focused, though. Add in that he's the least favorite "Type" or Red Ranger and it's just two simple pieces to this particular puzzle.

Concerning Kyoryuger, people don't actually dislike it. Daigo gets a lot of hate, but people still really enjoy Kyoryuger, including the crowd that don't like King. Souji and Nossan are legitimately good characters, Ian is kind of a 2010 version of Gai/Black Condor, Utsusemimaru (Okay spellcheck, tell me why THAT isn't considered a misspelled word...) was pretty cool for the first 10 episodes he appeared in, and people think Ami and KyoryuViolet II (I don't really remember her name) were cute (If someone could tell me Ami's particular story, I'd love to know). They were just caught up in a series that was absorbed by a substantially less interesting character.
