ET actually wasn't as bad as Raiders of the Lost Ark, but that game just never had popularity enough to be hated as much as ET.
I actually found ET pretty easy, but maybe I'm just a better gamer than most people. =) Centipede was the bomb tho!
As for ratings, I'd say 6/10 - some controls (lifting neck to elevate) were oversensitive, movie-based game didn't really follow story all that well. Yet, I've played much worse 2600 games.
