I get that you don't like ET.... I'm gonna take the liberty in guessing you've also never been on the ride
I don't get your point though...we were just stating which characters we'd like to see do meet and greets around the park. I'd want to see ET.....I love ET. I never said it was realistic, but I still would love to meet ET.
And as our dear Krusty pointed out, a closed attraction doesn't mean those characters can't meet anymore. Fievel, Doc Brown, and Lucy all still meet even though their attractions have long closed.
