Factual error: Spoiler: I saw this with two nurses who pointed this out, so I know this is correct. The final sequence takes place in a hospital room in ICU. Jill pulled out IVs and electrodes that were attached to her, then proceeded to Sydney's room. She pulled the call button, then tossed Sydney around the room. Glass shatters. She knocked Dewey out with a bedpan, fired a couple of shots from a gun, and yelled at Sydney, Gail, and the deputy. Sydney even fired the gun at one point. All of this goes on for quite some time, making a hell of a racket in ICU. The problem? The medical staff and security. Any nurse at the nurses' station would have been alerted automatically when Jill pulled the electrodes off herself, and also when the call button was pulled from the wall in Sydney's room. Within seconds there should have been someone come to the rooms to see why they were alerted, but the only time you see a nurse was when Jill hid just inside a door while making her way to Sydney's room. One walked past on her way somewhere as if nothing unusual was occurring. The subsequent fight occurs and you still don't see any hospital staff. So where were they?

Suggested correction: The answer to "Where were they", is; "at the mandatory meeting for all non-emergency personnel in the basement conference room." No, I am not joking, it's a message that you can faintly hear in the background (and the subtitles make sure to include it) from the hospital IP speakers. It's ludicrous and I am not saying that it corrects the entry, especially since it does not cover the fact that there should be automatic alerts and some personnel is on duty at their stations as precisely described, but just saying that the script somehow wanted to set up / justify it.
I'm changing the type to "Factual Error" to cover this. It's not a plot hole, it's just a really, really, really, really, really, REALLY badly run hospital as far as security is concerned. And if the hospital seen in the following 'Scream (2022) ' is the same one, it's just further evidence that it's simply a really crummy hospital.
It's worth noting that this emergency meeting announcement can only be heard in the alternate "pay per view" version of the movie. It is not present in the original US theatrical version.

Audio problem: When Jill reveals herself as the second killer, we hear Sidney say "Jill". But her mouth doesn't move.
Suggested correction: You can say "Jill" without moving your mouth.

Other mistake: Jill's shoulder seems to be perfectly fine when fighting with Sydney, even though she stabbed her shoulder earlier. (01:38:00 - 01:40:00)
Suggested correction: Anger and fear can be more than enough to gather enough strength to fight your way out of a difficult situation regardless of how much of a critical condition you are in.

Scream 4 (2011)
Corrected entry: In the scene where Jenny is trying to crawl under the garage door, the door is shut on her and we hear a sound that is supposed to be her bones breaking. If her back or spine were broken, she wouldn't have been able to crawl forward and fight the killer (and if her back was broken, she would have immediately passed out). It should be the garage door closing sound we hear, not a "bones breaking" sound.
Correction: Since we do not know for sure the extent of her injury, it is impossible to tell whether she'd still be able to fight the killer or not. People have also been known to be fully conscious for a short time after having their backs broken.

Scream 4 (2011)
Corrected entry: [Bit of a spoiler alert so don't' read any further if you haven't seen the movie yet.] At the end of the movie Sheriff Dewey tells the person who is the killer that Sidney is in critical condition and may or may not live but a few seconds later we see Sidney awake and alert and with enough strength to fight off the killer once again.
Correction: Anger and fear can be more than enough to gather enough strength to fight your way out of a difficult situation regardless of how much of a critical condition you are in.
True, but you can't have a lot of anger and fear if you are unconscious. The way the situation was presented, was that the doctors weren't even sure she was going to make it. It is part of the suspension of disbelief in movies to be very lenient with injuries and their implications, but this is really pushing it.

Scream 4 (2011)
Corrected entry: WARNING: Lots of spoilers! Throughout the entire movie, but mostly in the end, it's made apparent how much smaller Jill is than Sydney and the rest of the adult cast (watch her height and size compared to others, especially when she is laying next to Sydney at Kirby's house and the hospital). Charlie is shown to be the same height as Jill, most noticeable at Kirby's house when they kiss. However, in the scene where the cops are killed outside of Jill's house, the killer is taller than the cop. Not possible seeing as Jill and Charlie are both kinda small.
Correction: I wondered about this too, but then it occurred to me that Jill could simply have worn platform shoes whilst in the costume to make herself appear taller. This would help towards nobody suspecting her because, as you said, she is much smaller than Sydney.

Scream 4 (2011)
Corrected entry: In the end, approx 15 min before end the guy with the head camera goes to the balcony with bottle of light brown liquid but on the balcony he is drinking from the small (pocket size) bottle.
Correction: I just watched this scene and the bottle remains the same size throughout, it never changes.
