So, why is Saw X being praised by critics?

That's not a jab at the movie at all. Saw X is insanely great, fun and it's the best of the series imo.

However, the good reviews make me really curious. Not that critics should matter to a franchise like Saw ( I would always watch the movie, no matter what ), but what this movie has that the others don't?

For example, Saw 1, 2 and 6 also deserved great critics, but they were all rotten. Even the first Saw.

Thoughts?
