Ebert reviewed the film "Aliens" in 1987. Here are some highlights from his critique:
"This movie stands alone, however, as a self-contained story. and in some ways, this is probably better than the original.
"On the one hand, it's very well made...The special effects are outstanding: the movie is scary, and horrifying, and disgusting from one end to the other and I have nothing but admiration for its craftsmanship. But on the other hand, and this is a big but, at the end of the movie I felt really bad...Aliens was so strong, it was overkill. It really did upset me. So as a movie critic, I'm giving it thumbs up. I think its a good thriller. But if I were talking to a friend i think i'd say 'hey, I'm not sure you want to see this movie -- what kind of mood are you in?'."
