the bit where they pointed the gun at the baby really, really upset me. moreso than anything else that happened. even though they didn't actually fire the gun, the threat of it made me audibly gasp in shock.
that whole scene was a bit too much, I thought, too many horrible things happening. it was overwhelming for a horror film.
(MORE SPOILER!!)
me and my flatmate got a bit too into it when the baby's dad killed the mutant things. we were proper cheering him on.
