@Hicks I think it would be if they hadn't set it up. But it really works for me and doesn't insult us as much as the magic egg in 3. That was cheap - we're always searching for reasons for that on here, but out of the insane world of AvP Fandom, I remember sitting in the cinema (having seen Aliens a brazilion times at the movies and on video) thinking "WTF" - there was absolutely no logic to that.
You know, I've attacked 3 for treating the characters poorly - but Hicks and Newt aside - even I accept its a great arc for Ripley. But its undone in the first shot by having something that was not established. There wasn't even a flashback to a reprogrammed Bishop resorting to his primary directive or something like that. Or he didn't even say "Look, about the egg..." when he was part head part milky groundsheet (or if he did, I can't remember... traumatic amnesia or something).
It was just "there must have been an egg on there." NO! There wasn't *lol*.
The dream handwave is small beer compared to that leap of over the chasm of bollocks excuses in my book.
It's not great, but if they're going to acknowledge the others... it works just fine for me. And I think the vast majority of casual fans will get it too?
