The movie was great people who disliked it probly cant think too critically about it or dont know enough to understand why its so good lmao one reviewer asking what the chip did? No it wasnt to turn the power back on lmao it was to get the satellite dishes working again to communicate across the world smh if u didnt like this movie then u didnt deserve to watch it. My only gripe is that they did kill off people unnecessarily just for that emotional heartbreak that i guess there arent enough in the movie? Movies dont have to have more tragedy than necessary i believe since we are paying to have a good time.
