I loved it, not scarey at all imo, no drops just feels like you are floating, very very fun, usually I am very claustrophobic( do not do tom sawyer caves) but it didn't bother me at all...the screen is in front of your face kind of like a window and it does not feel stuffy nor confining imo. husband got very very sick even doing everything he was told to do and felt rotten for the rest of the morning( first thing we went on naturally) I have some balance problems but it did not bother me ( upside down coasters do, I walk like I'm drunk for a while after wards!). I do not think of it as a thrill ride like RNR or TOT..totally different sensation but maybe as "scarey" as say pirates or malestrom...pretty tame in other words with a couple of little "surprises"
if you are prone to motion sickness,,better to be safe than sorry and take something before hand, otherwise I doubt you'd have a problem if you ususlly do not ( husband is frequently actually green on glass bottom boats, any spinning rides ect and this was no exception but since he was "sure " he 'd be fine foolishly didn't take precautions!)
