When Zerdin got his contract to play at Planet Hollywood, an article wondered if there was enough interest for three ventriloquists on the Strip. I think the answer is no.
I enjoyed the show but I've seen much of what Zerdin does in the other 2 ventriloquist shows on the Strip.
Zerdin is talented and there's one point in the show where he shines--when he seems to be saying two things at once.
As for the couple on the stage, I've seen that done as a solo act and I just wasn't into the nature of that segment.
