"Although the aliens still have that nasty way of bursting through people's skin, mostly we meet them full-grown, with scales and coils and, my, what big teeth. Now they look like dragons, now like sea monsters or pterodactyls or a combination plate of lizard, bat, eel and spider. The young aliens resemble agitated lobsters. I thought I saw an elephant trunk on the Big Mamma alien, who is too big to be blown away even by Miss Weaver's big gun, but it could have been something else. Anyhow, it wasn't anything you'd want clutching at your foot while you were trying to hang on to your spaceship and not be gulped into the void. No monster movie with pretensions can do without a scene that stirs a twinge of compassion for the monsters. It might be just my wishful imagination, but I thought I detected an expression of anguish on Big Mamma, a prodigious breeder, as dozens of her extra-large eggs were getting badly cracked. But she could merely have been opening her glacierlike jaws to devour that little girl."
