Just got back from seeing this and I loved- but I feel you do need to watch it with adjusted expectations. The inconsequential kills, the fact that Chad survived (I'm glad he did- maybe not make the attack so life-threatening, or show more of the reactions than the actual stabbings?), the needless campery of Mulrooney's character- there was a fair bit of eye-rolling from me. But there was more than enough to love:
-Gale. Everything about her, but her interplay with Kirby and also with the killer (her putting them on hold is one of the finest moments of the series) were particular highlights.
-Chad. Yes, he's a snack, but a very well-rounded one and his tenderness with Tara felt so genuine.
-Hints at Sam's dark side.
-The subway scene.
Given how camp most of the film was, I actually felt Bailey should have been a lot more serious in the final act, to balance things out. Some of Mulrooney's delivery felt like he was trying to emulate Laurie Metcalf.
It's fairly low on my current ranking, given how the stakes felt so much higher in 5cream, though I think it will rise after a 2nd viewing. For me, it's currently a case of high stakes vs camp, iconic moments:
Scream 4 (the fact that I barely remember much of this one puts it last).
