I'm going to "rant" about the Ultra Warp Ride in Pokemon Ultra Sun/Moon for a second.
This is a pretty good idea, but the controls are just plain weird. You move around very slowly and there's a ton of obstacles (or whatever those weird electric orbs are supposed to be) to slow you down. Also, the wormholes are too big and you can often accidently go into one, messing you up. Also, it's very often that you will encounter the same non-legendary pokemon in one of the Ultra Space Wilds wormholes, which is ridiculous.
