So we've ridden both and like the new theme better. Happier vibe, better music and better animatronics. Just our opinion.I'm probably being a bit harsh because Splash Mountain was one of my favorite rides. The comments on the video I watched (side by side comparison with Splash Mountain) were pretty negative overall. But I'd probably have to ride it to get a better sense of the ride.
(Obvious spoilers if anyone is planning to ride it)
