(Sorry for bad english)
Hey, I have some movie scenes/plots i remember and would like to know of.

1. A movie about a world where kids have turned evil and killed their parents and I think a scene involves the protagonists who are adults needs to find something in a school or something like that. The kids find them and want to kill them.

2. Horror movie early 2000/ late 90s. A group of teenagers enters an asylum or an old hospital where there was a plague or something that killed everyone. A scene involves one of the main characters in a shower and orange goo ish stuff comes out of the showerhead. The bad guy rolls a trolley with bodies or something around. The ending is like they manage to leave the hospital but end up going back in because they’re infected or something.

3. A movie about catastrophes, showcasing selveral different ways the world could end, i remember one was a pandemic and was was a synthetic black hole. I saw ot around late 00s 09 maybe.

4. A zombie movie. The one and only scene i remember was that one guy sacrificed himself by getting eaten, graphic eating scene, so the other survivors could escape in a deescalating platform that went into the ground to a tunnel.

Thanks in advance.
