I just do not understand the complaints here. The head (apart from the spikes) was a perfect tweak IMO. The arms ? Who gives a f**k if a 20 ft creatures arms are 2mm to the right ? The body ? Never noticed. Every Alien creature design looks like a lot of random tubes and black muscle to me anyway, whats the difference ? The neck ? This I especially dont get. Theres more bitching about the neck than anywhere else and frankly I cant even spot the difference in the comparison photos.
The only part where the Aliens queen looked definitively better for me, was the feet. Thats all.
I didnt like the cg of the queen, but considering the ferocity of its actions there was no alternative at the time. Thats how it is in film making. There's usually not enough time and in Andersons case, enough of a budget aswell, to do everything the way you want it. He did a pretty good job with what he had IMO, considering he had to make a film that was appealing to new-comers of the franchise, respectfull to Pred fans (though Celtics death still pisses me off a little) and most difficult of all, respectfull to Alien fans.
He could've made Requiem, he didnt. He could've changed how both species work and directly contradicted everything about the previous movies, he didnt.
Just be thankfull then, thats it wasn't Robert Rodriguez who made the movie, or you would've been watching a Super Duper Uber Queen, who glows in the dark, has lazers for eyes, no eyebrows, four arses, a terrible fear of stamps and when she roars she sounds like Liam Neeson chasing a bunch of chickens around inside of a barrel.
