I don't know if anybody spotted this already, but how did the killer get from Aunt Kate's house to Kirby's so must faster than Sidney?
Ghostface kills Aunt Kate, then Sidney runs into Hicks for a minute, then she speeds off to Kirby's house. Moments later, Charlie and Jill are both at Kirby's with 30 minutes to spare before Sidney ever arrives.
Am I missing something? Sloppy film-making? 3rd killer?
Good point and a great eye for detail. I personally never thought anything of this until now.
I don't think that you're missing anything. IMO, it's just sloppy film-making. There were SO many sloppy things in this film that just irk me. Although Scream 4 was a decent entry to the series, again IMO, the whole film was just a missed opportunity. Don't get me wrong, there were some pretty cool parts to the film -- but a lot of recycled things from past films as well.
It's pretty sad that us fans put more thought into details than the actual team making the film.
