Doesn't that defeat the whole purpose of the shot? Sure, it's hard to spot what's going on, but there is merit to it. "Oh, god. What just happened?" can be a lot more effective. The more you see the Alien doing it's thing, the more comfortable one will be with it.
This I happen to agree with - I say keep the face-hugger shot at the proper speed.
