This could possibly do well for a sequel or the conclusion of the second trilogy.
A High School Reunion for Woodsboro. It would have a preponderance of backstory which would fit right in for the rules of a successful horror trilogy. Hicks would be there since she went to school with Sid and could bring her special brand of creepy sweetness. Other Woodsboro classmates would be there (possibly cameos from the guys and girls from the original Scream party at Stu’s). I just think it’d be interesting to have a Scream movie that involved mostly adults instead of teenagers since the franchise bends the rules every now and again.
Possible return of Kincaid as Sid’s plus one that she calls awkwardly a little at the last minute?
