I didn't think it was bad at all. The backwards part did concern me a bit before my wife and I rode it in January (AP preview), but it was cake. There are no really big drops in the backward section, just quick turns and small drops designed to take your breath away.
When you start forward again, there is one large drop at the end of the ride, but it REALLY didn't seem nearly as bad as the specs describe it to be.
And your attention will be on the Yeti anyway. That is one cool animatronic.
