Wow. I didn't watch this and I'm glad I didn't after reading this review.
"Well, there you have it: the possible conclusion of the Scream franchise, which will be remembered as the television equivalent of a wet fart in the annals of horror. The lengthy delay between seasons (almost three years) should have been all we needed to know: this “Three-Night Event’ was VH1’s way of dumping a turd of a season and wiping their hands clean. But their hands are not clean. Not. One. Bit."
Apparently this was the third season or there had been two seasons of a Scream show prior and someone made this one. It was only like six episodes aired 2 a night for 3 nights. And from the review, it was terrible, so doesn't seem like we missed anything.
