Meh. I used to think Sidney dying would be cool, but I realize it'd be a total flip-off to the fans.

Like she's the ultimate heroine, she can't ****ing die NOW lol. There's like no point to that. The only thing they need to do is work STAB out of the equation, kick up the extremes like they did in Scream 2 and make it epic. Also they need a fresher killer/motivation. Sidney's blood line coming after her is a little tired.
Gale would probably be the most effective death.
