^ I didn't see the premiere episode with the intros. But even if I did, I'd have forgotten everything (short term memory here). Without a scripted & filmed intro in the beginning of each episode, it's just a bunch of people in a big rush making plenty of noises. Sometimes I find it annoying, I didn't even want to hear their babbling. I do like the travel element, it shows exotic places and put them in an interesting context.
I'm much better in following talent shows, I remember their acts and they have more personality to me that way. There're also recaps and specially filmed intros with each episode, so they're more branded.
