Space Mountain at Disney Paris has a 54" height requirement, a launch and three inversions, so there's that. I'd count RnRC and ToT along with Journey to the Center of the Earth at DisneySea, I'll even give them Indiana Jones Adventure, Everest and California Screamin'. So there's 7 true thrill rides taking all of their parks into account... the rest are fairly family friendly (I see 4 and 5 year olds riding them).
But I agree that Disney has no idea what an actual thrill ride is. I'd love to see them take Bald Mountain and build a thrill machine coaster in Fantasyland - 54" height requirement, immersive theming, on-board music from Fantasia, Chernabog AA/projection chasing you throughout the ride, a few inversions in the pitch darkness, 150 foot drop backwards (with a launch as Chernabog is flying towards the car rolling backwards)... THAT's a thrill ride!! Fire Mountain in Adventureland could be a great addition as well.
Something to equal Hulk, Dueling Dragons, Popeye, Dudley, Spider-Man, FJ, MIB, Mummy, Gringotts, even a family dark ride with the craziness of Cat could be cool - Disney just hasn't shown the drive to build cutting edge thrill rides. MK only has 7 attractions out of 40-50 with a height requirement. Speedway, Barnstormer and SDMT are under 40" so they're more for the preschool/kindergarten crowd. Stitch is 40" for slight intensity, but it's a terrible attraction so I wouldn't recommend anyone go on it
So MK has 3 rides that could be classified as thrill rides. A few more E-ticket thrill rides wouldn't hurt and would actually help draw in more demographics. Disneyland has 4 (Indy, Splash, Big Thunder and Space - maybe 5 if you include Matterhorn which has only a 35" height requirement so I don't)
