I don't find the Mummy scary at all, and I was really afraid of the "launch" before I rode it. It is a very smooth ride and the drops are minimal. It is MUCH smoother than BTMR (I think that is an awful ride). ROTM reminded me of Space Mtn but smoother, my friend thought it a lot like RNR but I have not been to MGM so I can't compare. It didn't make my stomach do any flip-flops. I thought it a little mild but a very fun ride.
