ET is Universal's last audio-animatronics spectacle, with Kong gone, Mummy meh (as far as animatronics go), and River Adventure half-decrepit... and it's one of the few major rides with no height requirement that everyone in the family can ride. E.T. is also a childhood, nostalgic icon for many Americans - and a Spielburg classic. For these reasons, E.T. Adventure should never be removed. (But a nice upgrade would be cool.)
