To answer the question of why people want Halloween 2.0 or yet another Walking Dead - people are unimaginative. They have very little idea of what they actually want - most aren't creatives capable of developing/selecting new ideas/properties - so they request the most benign, predictable ideas since they're the most immediate and accessible concepts to them.
I wouldn't mind a sequel or two, but here's hoping it isn't just an unnecessary redux of prior successes. Let A&D flex and create something new. After all these forced IPs, I think they've earned it.
