But they have no problem skewering it before it opens? Seems like backwards logic to me. Either you withhold all judgement before it opens or you are free to complain and praise based on what you do know.
Being skeptical and not giving it praise before it opens is not "skewering" the attraction. With this attraction, I withhold total judgment until I experience it myself.
Because with or without it they'd still be many many steps above what has normally be done. I didn't say they were the best conceivable I said they were the best in existence. And I still say they're worthy of that label and if not still would be at #2 or #3. No one is complaining that Everest's trains have no lights or that the cars are basically painted boxes yet here you're getting a lot more and it's still not enough.
How can you say it's the best in existence when you haven't been on the ride yet? You've only seen a video. That's not enough evidence. You're free to your opinion, but it's way too early to be declaring that, especially when there are several other attractions with detailed ride vehicles in existence today.
I certainly didn't assert the ride was an e-ticket nor have many others outside of the Disney marketing machine. And really do you expect Disney to say "here's our newest ride - but yeah it's not that cool you really shouldn't pay attention to it all that much. Wait till 2017 or go to carsland"? It's never been claimed to be more than a coaster for families and people of all ages with a thrill factor between barnstormer and BTM with an immersive environment.
I personally am a bit disappointed in the content of Disney's rides lately (though I feel it's more about trying too hard to hit certain demographics and ideals rather than any sort of ineptitude ). I would have loved the mine coaster to be more than it is and more in line with the blueprints leaked above. However as you yourself pointed out Disney has done a superb job lately with "immense detail and eloquent environments" and I'm ok with giving credit where it's due even if the attraction looks to be a rather short timid coaster with only one big scene. So yes best or nearly best themed ride cars ever regardless of whether or not the bloody lanterns light.
Tower of Terror, Radiator Springs Racers, Test Track, Journey to the Center of the Earth, 20,000 Leagues Under the Sea, Jungle Cruise, Kilimanjaro's Safari, WDW Railroad, Wildlife Express Train, Liberty Bell and so on. It's not accurate to put 7DMT on a pedestal just yet. We should wait to ride it, because as you agreed, Disney is going to hype everything because they want you to take notice. Don't you think therefore, they would over-hype these ride vehicles, hence why there was a promotional video about them?
You might not have called it an E-ticket attraction (nobody claimed you did) however you are asserting that we will be getting the best themed ride cars, a la E-ticket quality ride cars. If I had to choose, I would rather have an E-ticket quality attraction with C or D ticket level ride vehicles/environments, then the other way around. Naturally it would be nice if Disney could combine the two again like they used to.
But like I said before, I'm not rooting for this to fail. I want it to succeed, but you have to understand that skepticism before riding and withholding praise before riding is not a negative against the attraction. I would say it's common sense.
