Ehh...not for sure. Have you visited most of the CF parks? Those are good parks you mentioned, but most of the cool-factor merely suggests the big coasters they've added in recent years. If that's all it takes, we'd be more welcoming toward parking lot coasters. Wonderland is also on par with those parks, too, but the giant coaster philosophy isn't the only way to become a cool brother -- look at Knott's!
I'm going to stick up for the other Cedar Fair parks. They may not be global draws, but they're generally clean and appropriate for their markets. I think some people get a mindset that parks are either adding giga coasters or knocking on death's door, with nothing in between. In this way, Cedar Point & SFMM are bad examples from which to set expectations and define what makes a good park.
For example, the GCI additions to Valleyfair, CGA, WoF, & KI, as well as the Ghostrider rehab, are really good coasters -- it's ignorant to use this bastard-talk to paint a negative image of parks that are maintaining themselves and adding fun. I know you didn't say this, but it comes off as a sour grapes way of rejecting what you got because of what you didn't get for Christmas. I feel like there's an unfair sentiment of laughing off any park that doesn't have its giga coaster or RMC by now.
I think you didn't catch the exaggeration and the sarcasm in all this family metaphor. In fact, I have never been to any Cedar Fair park, as I'm from Spain and I've never been outside of Europe, but I just played with the global conception people has about the other parks in the chain.
I completely agree with what you said: an RMC or giga isn't necessary, but keep in mind that was a comparison game, where the generalization wasn't meant to be a real definition, just a way of making fun about what the community thinks.
